+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+
+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL. It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it. You can use it for
+your libraries, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library. If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software. To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+ Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs. This
+license, the GNU Library General Public License, applies to certain
+designated libraries. This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+ The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it. Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program. However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+ Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries. We
+concluded that weaker conditions might promote sharing better.
+
+ However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves. This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them. (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.) The hope is that this
+will lead to faster development of free libraries.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+ Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License"). Each licensee is
+addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ c) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ d) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ Appendix: How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+
+ Copyright (C)
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Library General Public
+ License as published by the Free Software Foundation; either
+ version 2 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Library General Public License for more details.
+
+ You should have received a copy of the GNU Library General Public
+ License along with this library; if not, write to the Free
+ Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+Dependencies
+
+ Reguires EGL 1.4 or later. This extension is written against the
+ wording of the EGL 1.4 specification.
+
+ EGL_KHR_base_image is required.
+
+Overview
+
+ This extension provides entry points for integrating EGLImage with the
+ Linux DRM mode setting and memory management drivers. The extension
+ lets applications create EGLImages without a client API resource and
+ lets the application get the DRM buffer handles.
+
+IP Status

+
+New Procedures and Functions
+

+
+ Use when importing drm buffer:
+
+ EGL_DRM_BUFFER_STRIDE_MESA 0x31D4
+ EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
+
+Additions to the EGL 1.4 Specification:
+
+ To create a DRM EGLImage, call
+
+ EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
+ const EGLint *attrib_list);
+
+ In the attribute list, pass EGL_WIDTH, EGL_HEIGHT and format and
+ use in the attrib list using EGL_DRM_BUFFER_FORMAT_MESA and
+ EGL_DRM_BUFFER_USE_MESA. The only format specified by this
+ extension is EGL_DRM_BUFFER_FORMAT_ARGB32_MESA, where each pixel
+ is a CPU-endian, 32-bit quantity, with alpha in the upper 8 bits,
+ then red, then green, then blue. The bit values accepted by
+ EGL_DRM_BUFFER_USE_MESA are EGL_DRM_BUFFER_USE_SCANOUT_MESA and
+ EGL_DRM_BUFFER_USE_SHARE_MESA. EGL_DRM_BUFFER_USE_SCANOUT_MESA
+ requests that the created EGLImage should be usable as a scanout
+ buffer with the DRM kernel modesetting API. The
+ EGL_DRM_BUFFER_USE_SHARE_MESA bit requests that the EGLImage can
+ be shared with other processes by passing the underlying DRM
+ buffer name.
+
+ To create a process local handle or a global DRM name for a
+ buffer, call
+
+ EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
+ EGLImageKHR image,
+ EGLint *name,
+ EGLint *handle,
+ EGLint *stride);
+
+ If is non-NULL, a global name is assigned to the image and
+ written to , the handle (local to the DRM file descriptor,
+ for use with DRM kernel modesetting API) is written to if
+ non-NULL and the stride (in bytes) is written to , if
+ non-NULL.
+
+ Import a shared buffer by calling eglCreateImageKHR with
+ EGL_DRM_BUFFER_MESA as the target, using EGL_WIDTH, EGL_HEIGHT,
+ EGL_DRM_BUFFER_FORMAT_MESA, EGL_DRM_BUFFER_STRIDE_MESA
+ in the attrib list.
+
+Issues
+
+ 1. Why don't we use eglCreateImageKHR with a target that
+ indicates that we want to create an EGLImage from scratch?
+
+ RESOLVED: The eglCreateImageKHR entry point is reserved for
+ creating an EGLImage from an already existing client API
+ resource. This is fine when we're creating the EGLImage from
+ an existing DRM buffer name, it doesn't seem right to overload
+ the function to also allocate the underlying resource.
+
+ 2. Why don't we use an eglQueryImageMESA type functions for
+ querying the DRM EGLImage attributes (name, handle, and stride)?
+
+ RESOLVED: The eglQueryImage function has been proposed often,
+ but it goes against the EGLImage design. EGLImages are opaque
+ handles to a 2D array of pixels, which can be passed between
+ client APIs. By referenceing an EGLImage in a client API, the
+ EGLImage target (a texture, a renderbuffer or such) can be
+ used to query the attributes of the EGLImage. We don't have a
+ full client API for creating and querying DRM buffers, though,
+ so we use a new EGL extension entry point instead.

+ OpenGL 1.0 or later is required
+ This extensions is written against the OpenGL 1.4 Specification.
+
+Overview
+
+ This extension adds a new pixel storage parameter to indicate that
+ images are to be packed in top-to-bottom order instead of OpenGL's
+ conventional bottom-to-top order. Only pixel packing can be
+ inverted (i.e. for glReadPixels, glGetTexImage, glGetConvolutionFilter,
+ etc).
+
+ Almost all known image file formats store images in top-to-bottom
+ order. As it is, OpenGL reads images from the frame buffer in
+ bottom-to-top order. Thus, images usually have to be inverted before
+ writing them to a file with image I/O libraries. This extension
+ allows images to be read such that inverting isn't needed.
+
+IP Status
+
+ None
+
+Issues
+
+ 1. Should we also defined UNPACK_INVERT_MESA for glDrawPixels, etc?
+
+ Resolved: No, we're only concerned with pixel packing. There are other
+ solutions for inverting images when using glDrawPixels (negative Y pixel
+ zoom) or glTexImage (invert the vertex T coordinates). It would be easy
+ enough to define a complementary extension for pixel packing in the
+ future if needed.

+Overview
+
+ Since Mesa allows RGB rendering into drawables with PseudoColor,
+ StaticColor, GrayScale and StaticGray visuals, Mesa needs a colormap
+ in order to compute pixel values during rendering.
+
+ The colormap associated with a window can be queried with normal
+ Xlib functions but there is no colormap associated with pixmaps.
+
+ The glXCreateGLXPixmapMESA function is an alternative to glXCreateGLXPixmap

+

+
+ The function
+

+ Mesa 2.2 or later is required.
+
+Overview
+
+ Mesa is often used as a client library with no integration with
+ the computer's window system (an X server, for example). And since
+ Mesa does not have an event loop nor window system callbacks, it
+ cannot properly respond to window system events. In particular,
+ Mesa cannot automatically detect when a window has been resized.
+
+ Mesa's glViewport command queries the current window size and updates
+ its internal data structors accordingly. This normally works fine
+ since most applications call glViewport in responce to window size
+ changes.
+
+ In some situations, however, the application may not call glViewport
+ when a window size changes but would still like Mesa to adjust to
+ the new window size. This extension exports a new function to solve
+ this problem.

+
+ The printMESA function writes the argument to the "debug

+
+ The assertMESA function checks if the argument is
+ true or false. If it is true, nothing happens. If it is false,
+ a diagnostic message is written to the "debug assert log".
+ The message contains the argument , , and
+ implementation dependent double-quoted string, each of this
+ delimited by a white space. If the argument is not present,
+ it is meant as if it was of value 0. If the arguments and
+ are not present, they are meant as if they were of values

+ [Add the following to Section 3.3.10 of the GLX Specification (Double
+ Buffering)]
+
+ glXSwapIntervalMESA specifies the minimum number of video frame periods
+ per buffer swap. (e.g. a value of two means that the color buffers
+ will be swapped at most every other video frame.) A return value
+ of zero indicates success; otherwise an error occurred. The interval
+ takes effect when glXSwapBuffers is first called subsequent to the
+ glXSwapIntervalMESA call.
+
+ A video frame period is the time required by the monitor to display a
+ full frame of video data. In the case of an interlaced monitor,
+ this is typically the time required to display both the even and odd
+ fields of a frame of video data.
+
+ If is set to a value of 0, buffer swaps are not synchron-
+ ized to a video frame. The value is silently clamped to
+ the maximum implementation-dependent value supported before being
+ stored.
+
+ The swap interval is not part of the render context state. It cannot
+ be pushed or popped. The current swap interval for the window
+ associated with the current context can be obtained by calling
+ glXGetSwapIntervalMESA. The default swap interval is 0.
+
+ On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets
+ the swap interval to 1.

+
+ Based on WGL_I3D_swap_frame_usage version 1.3.
+
+Overview
+
+ This extension allows an application to determine what portion of the
+ swap period has elapsed since the last swap operation completed. The
+ "usage" value is a floating point value on the range [0,max] which is
+ calculated as follows:
+
+ td
+ percent = ----
+ tf
+
+ where td is the time measured from the last completed buffer swap (or
+ call to enable the statistic) to when the next buffer swap completes, tf
+ is the entire time for a frame which may be multiple screen refreshes
+ depending on the swap interval as set by the GLX_SGI_swap_control or
+ GLX_OML_sync_control extensions.
+
+ The value, percent, indicates the amount of time spent between the
+ completion of the two swaps. If the value is in the range [0,1], the
+ buffer swap occurred within the time period required to maintain a
+ constant frame rate. If the value is in the range (1,max], a constant
+ frame rate was not achieved. The value indicates the number of frames
+ required to draw.
+
+ This definition of "percent" differs slightly from
+ WGL_I3D_swap_frame_usage. In WGL_I3D_swap_frame_usage, the measurement
+ is taken from the completion of one swap to the issuance of the next.
+ This representation may not be as useful as measuring between
+ completions, as a significant amount of time may pass between the
+ issuance of a swap and the swap actually occurring.
+
+ There is also a mechanism to determine whether a frame swap was
+ missed.

+
+ The frame usage is measured as the percentage of the swap period elapsed
+ between two buffer-swap operations being committed. In unextended GLX the
+ swap period is the vertical refresh time. If SGI_swap_control or
+ MESA_swap_control are supported, the swap period is the vertical refresh
+ time multiplied by the swap interval (or one if the swap interval is set
+ to zero).
+
+ If OML_sync_control is supported, the swap period is the vertical
+ refresh time multiplied by the divisor parameter to
+ glXSwapBuffersMscOML. The frame usage in this case is less than 1.0 if
+ the swap is committed before target_msc, and is greater than or equal to
+ 1.0 otherwise. The actual usage value is based on the divisor and is
+ never less than 0.0.
+
+ int glXBeginFrameTrackingMESA(Display *dpy,
+ GLXDrawable drawable,
+ float *usage)
+
+ glXGetFrameUsageMESA returns a floating-point value in
+ that represents the current swap usage, as defined above.

+ Missed frame swaps can be tracked by calling the following function:
+
+ int glXBeginFrameTrackingMESA(Display *dpy,
+ GLXDrawable drawable)
+
+ glXBeginFrameTrackingMESA resets a "missed frame" count and
+ synchronizes with the next frame vertical sync before it returns.
+ If a swap is missed based in the rate control specified by the
+ set by glXSwapIntervalSGI or the default swap of once
+ per frame, the missed frame count is incremented.
+
+ The current missed frame count and total number of swaps since
+ the last call to glXBeginFrameTrackingMESA can be obtained by
+ calling the following function:
+
+ int glXQueryFrameTrackingMESA(Display *dpy,
+ GLXDrawable drawable,
+ int64_t *swapCount,
+ int64_t *missedFrames,
+ float *lastMissedUsage)
+
+ The location pointed to by will be updated with the
+ number of swaps that have been committed. This value may not match the
+ number of swaps that have been requested since swaps may be
+ queued by the implementation. This function can be called at any
+ time and does not synchronize to vertical blank.
+
+ The location pointed to by will contain the number
+ swaps that missed the specified frame. The frame usage for the
+ last missed frame is returned in the location pointed to by
+ .
+
+ Frame tracking is disabled by calling the function
+
+ int glXEndFrameTrackingMESA(Display *dpy,
+ GLXDrawable drawable)
+
+ This function will not return until all swaps have occurred. The
+ application can call glXQueryFrameTrackingMESA for a final swap and
+ missed frame count.
+
+ If these functions are successful, zero is returned. If the context
+ associated with dpy and drawable is not a direct context,
+ GLX_BAD_CONTEXT is returned.
+
+Errors
+
+ If the function succeeds, zero is returned. If the function

+
+Overview
+
+ There are a number of circumstances where an application may wish to
+ blend two textures out of a larger set of textures. Moreover, in some
+ cases the selected textures may vary on a per-fragment basis within
+ a polygon. Several examples include:
+
+ 1. High dynamic range textures. The application stores several
+ different "exposures" of an image as different textures. On a
+ per-fragment basis, the application selects which exposures are
+ used.
+
+ 2. A terrain engine where the altitude of a point determines the
+ texture applied to it. If the transition is from beach sand to
+ grass to rocks to snow, the application will store each texture
+ in a different texture map, and dynamically select which two
+ textures to blend at run-time.
+
+ 3. Storing short video clips in textures. Each depth slice is a
+ single frame of video.
+
+ Several solutions to this problem have been proposed, but they either
+ involve using a separate texture unit for each texture map or using 3D
+ textures without mipmaps. Both of these options have major drawbacks.
+
+ This extension provides a third alternative that eliminates the major
+ drawbacks of both previous methods. A new texture target,
+ TEXTURE_2D_ARRAY, is added that functions identically to TEXTURE_3D in
+ all aspects except the sizes of the non-base level images. In
+ traditional 3D texturing, the size of the N+1 LOD is half the size
+ of the N LOD in all three dimensions. For the TEXTURE_2D_ARRAY target,
+ the height and width of the N+1 LOD is halved, but the depth is the
+ same for all levels of detail. The texture then becomes an array of
+ 2D textures. The per-fragment texel is selected by the R texture
+ coordinate.

+
+ "In addition to image arrays for one-, two-, and three-dimensional
+ textures, one- and two-dimensional array textures, and the six image
+ arrays for the cube map texture, partially instantiated image arrays
+ are maintained for one-, two-, and three-dimensional textures and one-
+ and two-dimensional array textures. Additionally, a single proxy image
+ array is maintained for the cube map texture. Each proxy image array
+ includes width, height, depth, border width, and internal format state
+ values, as well as state for the red, green, blue, alpha, luminance,
+ and intensity component resolutions. Proxy image arrays do not include
+ image data, nor do they include texture properties. When TexImage3D is
+ executed with target specified as PROXY_TEXTURE_3D, the
+ three-dimensional proxy state values of the specified level-of-detail
+ are recomputed and updated. If the image array would not be supported
+ by TexImage3D called with target set to TEXTURE 3D, no error is
+ generated, but the proxy width, height, depth, border width, and
+ component resolutions are set to zero. If the image array would be

+ exactly as though the actual image array were being specified. No pixel
+ data are transferred or processed in either case.
+

+
+ -- Section 3.8.12 "Texture Objects"
+
+ Change section (page 180) to say (spec changes identical to
+ EXT_texture_array):
+
+ "In addition to the default textures TEXTURE_1D, TEXTURE_2D,
+ TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and TEXTURE_2D_EXT,
+ named one-, two-, and three-dimensional, cube map, and one- and
+ two-dimensional array texture objects can be created and operated upon.
+ The name space for texture objects is the unsigned integers, with zero
+ reserved by the GL.
+
+ A texture object is created by binding an unused name to TEXTURE_1D,
+ TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or
+ TEXTURE_2D_ARRAY_EXT. The binding is effected by calling
+
+ void BindTexture(enum target, uint texture);
+
+ with set to the desired texture target and set to
+ the unused name. The resulting texture object is a new state vector,
+ comprising all the state values listed in section 3.8.11, set to the
+ same initial values. If the new texture object is bound to TEXTURE_1D,
+ TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or
+ TEXTURE_2D_ARRAY_EXT, it is and remains a one-, two-,
+ three-dimensional, cube map, one- or two-dimensional array texture
+ respectively until it is deleted.
+
+ BindTexture may also be used to bind an existing texture object to
+ either TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP,
+ TEXTURE_1D_ARRAY_EXT, or TEXTURE_2D_ARRAY_EXT. The error
+ INVALID_OPERATION is generated if an attempt is made to bind a texture
+ object of different dimensionality than the specified target. If the
+ bind is successful no change is made to the state of the bound texture
+ object, and any previous binding to target is broken.
+
+ While a texture object is bound, GL operations on the target to which
+ it is bound affect the bound object, and queries of the target to which
+ it is bound return state from the bound object. If texture mapping of
+ the dimensionality of the target to which a texture object is bound is
+ enabled, the state of the bound texture object directs the texturing
+ operation.
+
+ In the initial state, TEXTURE_1D, TEXTURE_2D, TEXTURE_3D,
+ TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and TEXTURE_2D_ARRAY_EXT have
+ one-, two-, three-dimensional, cube map, and one- and two-dimensional
+ array texture state vectors respectively associated with them. In order
+ that access to these initial textures not be lost, they are treated as
+ texture objects all of whose names are 0. The initial one-, two-,
+ three-dimensional, cube map, one- and two-dimensional array textures
+ are therefore operated upon, queried, and applied as TEXTURE_1D,
+ TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and
+ TEXTURE_2D_ARRAY_EXT respectively while 0 is bound to the corresponding
+ targets.

+Issues
+
+ (1) Is "texture stack" a good name for this functionality?
+
+ NO. The name is changed to "array texture" to match the
+ nomenclature used by GL_EXT_texture_array.
+
+ (2) Should the R texture coordinate be treated as normalized or

+ of as a direct index into the array texture. This may be more
+ convenient for applications.
+
+ RESOLVED. All texture coordinates are normalized. The issue of
+ un-normalized texture coordinates has been discussed in the ARB
+ before and should be left for a layered extension.
+
+ RE-RESOLVED. The R coordinate is un-normalized. Accessing an array
+ using [0, layers-1] coordinates is much more natural.
+
+ (3) How does LOD selection work for stacked textures?
+
+ RESOLVED. For 2D array textures the R coordinate is ignored, and
+ the LOD selection equations for 2D textures are used. For 1D
+ array textures the T coordinate is ignored, and the LOD selection
+ equations for 1D textures are used. The expected usage is in a
+ fragment program with an explicit LOD selection.
+
+ (4) What is the maximum size of a 2D array texture? Is it the same
+ as for a 3D texture, or should a new query be added? How about for 1D
+ array textures?
+
+ RESOLVED. A new query is added.
+
+ (5) How are array textures exposed in GLSL?
+
+ RESOLVED. Use GL_EXT_texture_array.
+
+ (6) Should a 1D array texture also be exposed?
+
+ RESOLVED. For orthogonality, yes.
+
+ (7) How are stacked textures attached to framebuffer objects?
+
+ RESOLVED. Layers of both one- and two-dimensional array textures
+ are attached using FreambufferTextureLayerEXT. Once attached, the
+ array texture layer behaves exactly as either a one- or
+ two-dimensional texture.
+
+ (8) How is this extension related to GL_EXT_texture_array?
+
+ This extension adapats GL_MESAX_texture_stack to the notation,
+ indexing, and FBO access of GL_EXT_texture_array. This extension
+ replaces the GLSL support of GL_EXT_texture_array with
+ GL_ARB_fragment_program support.
+
+ Assembly program support is also provided by GL_NV_gpu_program4.

+ Written based on the wording of the OpenGL 2.0 specification.
+
+ This extension trivially interacts with ARB_texture_float.
+ This extension shares some language with ARB_texture_compression_rgtc
+ but does not depend on it.
+
+Overview
+
+ OpenGL prior to 3.1 does not support any signed texture formats.
+ ARB_texture_compression_rgtc introduces some compressed red and
+ red_green signed formats but no uncompressed ones, which might
+ still be useful. NV_texture_shader adds signed texture formats,
+ but also a lot of functionality which has been superceded by fragment
+ shaders.
+ It is usually possible to get the same functionality
+ using a unsigned format by doing scale and bias in a shader, but this
+ is undesirable since modern hardware has direct support for this.
+ This extension adds a signed 4-channel texture format by backporting
+ the relevant features from OpenGL 3.1, as a means to support this in
+ OpenGL implementations only supporting older versions.
+
+Issues
+
+ 1) What should this extension be called?
+
+ RESOLVED: MESA_texture_signed_rgba seems reasonable.
+ The rgba part is there because only 4 channel format is supported.
+
+
+ 2) Should the full set of signed formats (alpha, luminance, rgb, etc.)
+ be supported?
+
+ RESOLVED: NO. To keep this extension simple, only add the most
+ universal format, rgba. alpha/luminance can't be trivially supported
+ since OpenGL 3.1 does not support them any longer, and there is some
+ implied dependency on ARB_texture_rg for red/red_green formats so
+ avoid all this. Likewise, only 8 bits per channel is supported.
+
+
+ 3) Should this extension use new enums for the texture formats?
+
+ RESOLVED: NO. Same enums as those used in OpenGL 3.1.
+
+
+ 4) How are signed integer values mapped to floating-point values?
+
+ RESOLVED: Same as described in issue 5) of
+ ARB_texture_compression_rgtc (quote):
+ A signed 8-bit two's complement value X is computed to
+ a floating-point value Xf with the formula:
+
+ { X / 127.0, X > -128
+ Xf = {
+ { -1.0, X == -128
+
+ This conversion means -1, 0, and +1 are all exactly representable,
+ however -128 and -127 both map to -1.0. Mapping -128 to -1.0
+ avoids the numerical awkwardness of have a representable value
+ slightly more negative than -1.0.
+
+ This conversion is intentionally NOT the "byte" conversion listed
+ in Table 2.9 for component conversions. That conversion says:
+
+ Xf = (2*X + 1) / 255.0
+
+ The Table 2.9 conversion is incapable of exactly representing
+ zero.
+
+ (Difference to ARB_texture_compression_rgtc):
+ This is the same mapping as OpenGL 3.1 uses.
+ This is also different to what NV_texture_shader used.
+ The above mapping should be considered the reference, but there
+ is some leeway so other mappings are allowed for implementations which
+ cannot do this. Particulary the mapping given in NV_texture_shader or
+ the standard OpenGL byte/float mapping is considered acceptable too, as
+ might be a mapping which represents -1.0 by -128, 0.0 by 0 and 1.0 by
+ 127 (that is, uses different scale factors for negative and positive
+ numbers).
+ Also, it is ok to store incoming GL_BYTE user data as-is, without
+ converting to GL_FLOAT (using the standard OpenGL float/byte mapping)
+ and converting back (using the mapping described here).
+ Other than those subtle issues there are no other non-standard
+ conversions used, so when using for instance CopyTexImage2D with
+ a framebuffer clamped to [0,1] all converted numbers will be in the range
+ [0, 127] (and not scaled and biased).
+
+
+ 5) How will signed components resulting from RGBA8_SNORM texture
+ fetches interact with fragment coloring?
+
+ RESOLVED: Same as described in issue 6) of
+ ARB_texture_compression_rgtc (quote):
+ The specification language for this extension is silent
+ about clamping behavior leaving this to the core specification
+ and other extensions. The clamping or lack of clamping is left
+ to the core specification and other extensions.
+
+ For assembly program extensions supporting texture fetches
+ (ARB_fragment_program, NV_fragment_program, NV_vertex_program3,
+ etc.) or the OpenGL Shading Language, these signed formats will
+ appear as expected with unclamped signed components as a result
+ of a texture fetch instruction.
+
+ If ARB_color_buffer_float is supported, its clamping controls
+ will apply.
+
+ NV_texture_shader extension, if supported, adds support for
+ fixed-point textures with signed components and relaxed the
+ fixed-function texture environment clamping appropriately. If the
+ NV_texture_shader extension is supported, its specified behavior
+ for the texture environment applies where intermediate values
+ are clamped to [-1,1] unless stated otherwise as in the case
+ of explicitly clamped to [0,1] for GL_COMBINE. or clamping the
+ linear interpolation weight to [0,1] for GL_DECAL and GL_BLEND.
+
+ Otherwise, the conventional core texture environment clamps
+ incoming, intermediate, and output color components to [0,1].
+
+ This implies that the conventional texture environment
+ functionality of unextended OpenGL 1.5 or OpenGL 2.0 without
+ using GLSL (and with none of the extensions referred to above)
+ is unable to make proper use of the signed texture formats added
+ by this extension because the conventional texture environment
+ requires texture source colors to be clamped to [0,1]. Texture
+ filtering of these signed formats would be still signed, but
+ negative values generated post-filtering would be clamped to
+ zero by the core texture environment functionality. The
+ expectation is clearly that this extension would be co-implemented
+ with one of the previously referred to extensions or used with
+ GLSL for the new signed formats to be useful.
+
+
+ 6) Should the RGBA_SNORM tokens also be accepted by CopyTexImage
+ functions?
+
+ RESOLVED: YES.
+
+
+ 7) What to do with GetTexParameter if ARB_texture_float is supported,
+ in particular what datatype should this return for TEXTURE_RED_TYPE_ARB,
+ TEXTURE_GREEN_TYPE_ARB, TEXTURE_BLUE_TYPE_ARB, TEXTURE_ALPHA_TYPE_ARB?
+
+ RESOLVED: ARB_texture_float states type is either NONE,
+ UNSIGNED_NORMALIZED_ARB, or FLOAT. This extension adds a new enum,
+ SIGNED_NORMALIZED, which will be returned accordingly. This is the
+ same behaviour as in OpenGL 3.1.

+ OpenGL 1.0 is required.
+ The extension is written against the OpenGL 1.2 Specification
+
+Overview
+
+ In order to set the current raster position to a specific window
+ coordinate with the RasterPos command, the modelview matrix, projection
+ matrix and viewport must be set very carefully. Furthermore, if the
+ desired window coordinate is outside of the window's bounds one must
+ rely on a subtle side-effect of the Bitmap command in order to circumvent
+ frustum clipping.
+
+ This extension provides a set of functions to directly set the
+ current raster position, bypassing the modelview matrix, the
+ projection matrix and the viewport to window mapping. Furthermore,
+ clip testing is not performed.
+
+ This greatly simplifies the process of setting the current raster
+ position to a specific window coordinate prior to calling DrawPixels,
+ CopyPixels or Bitmap.

+
+ This extension supports texture images stored in the YCbCr format.
+ There is no support for converting YCbCr images to RGB or vice versa
+ during pixel transfer. The texture's YCbCr colors are converted to
+ RGB during texture sampling, after-which, all the usual per-fragment
+ operations take place. Only 2D texture images are supported (not
+ glDrawPixels, glReadPixels, etc).
+
+ A YCbCr pixel (texel) is a 16-bit unsigned short with two components.
+ The first component is luminance (Y). For pixels in even-numbered
+ image columns, the second component is Cb. For pixels in odd-numbered
+ image columns, the second component is Cr. If one were to convert the
+ data to RGB one would need to examine two pixels from columns N and N+1
+ (where N is even) to deduce the RGB color.

+ 3Dfx Glide device driver
+
+
+
+Requirements:
+-------------
+
+A Voodoo-based videocard/accelerator
+DOS (with DJGPP), Windows9x/2k (with MinGW), Linux
+Glide3x library for your OS
+
+http://sourceforge.net/projects/glide/
+
+
+
+How to compile:
+---------------
+
+DJGPP:
+ Place the Glide3 SDK in the top Mesa directory:
+ $(MESA)/glide3/include/
+ 3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+ $(MESA)/glide3/lib/
+ libgld3x.a, libgld3i.a, glide3x.dxe
+ Type:
+ make -f Makefile.DJ X86=1 FX=1
+ Look into the makefile for further information.
+
+MinGW:
+ Place the Glide3 SDK in the top Mesa directory:
+ $(MESA)/glide3/include/
+ 3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+ $(MESA)/glide3/lib/
+ libglide3x.a, glide3x.dll
+ Type:
+ make -f Makefile.mgw X86=1 FX=1
+ Look into the makefile for further information.
+
+Linux:
+ Place the Glide3 SDK in /usr/local/glide
+ /usr/local/glide/include/
+ 3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+ /usr/local/glide/lib/
+ libglide3x.a, libglide3x.so
+ Type:
+ make linux-glide
+ or
+ make linux-x86-glide
+
+
+
+Compilation defines:
+--------------------
+
+FX_DEBUG
+ enable driver debug code
+FX_TRAP_GLIDE
+ enable Glide trace code
+FX_PACKEDCOLOR
+ use packed color in vertex structure
+FX_TC_NAPALM
+ map GL_COMPRESSED_RGB[A] to FXT1. Works with VSA100-based cards only.
+FX_COMPRESS_S3TC_AS_FXT1_HACK
+ map S3TC to FXT1
+FX_RESCALE_BIG_TEXURES_HACK
+ fake textures larger than HW can support
+ (see MESA_FX_MAXLOD environment variable)
+
+
+
+Environment variables:
+----------------------
+
+The following environment variables affect MesaFX. Those that affect Glide
+only, are beyond the scope of this section. Entries that don't have a "Value"
+field, can have any value whatsoever
+ ex: set MESA_FX_IGNORE_CMBEXT=y
+
+"Note" (*) means that the environment variable affects Glide, too; also, if
+the var is not found in the environment, it is searched in windoze registry.
+"Note" (!) means that the environment variable is not working as expected;
+may have undefined effects, might have effects only at Glide level or might
+not have any effect whatsoever. Caveat emptor! Those are to be revised soon.
+
+It is recommended to leave the envvars alone, so that Mesa/Glide will run with
+default values. Use them only when you experience crashes or strange behavior.

+Info for Mesa 4.1
+-----------------
+
+The 3dfx Glide driver in Mesa is disabled by default. Not too many people
+use this driver anymore and at some point down the road it will be dropped.
+
+To use/enable the Glide driver either do this:
+
+'./configure --with-glide=DIR' Where DIR is the location of Glide, like
+ /usr/ or /usr/local
+
+OR
+
+'make linux-x86-glide' If using the old-style Makefile system.
+
+The rest of this file hasn't changed since Mesa 3.3. Some of it's out of
+date, but some is still valid.
+
+
+
+What do you need ?
+------------------
+
+ - A PC with a 3Dfx Voodoo1/2 Graphics or Voodoo Rush based board
+ (Pure3D, Monster 3D, R3D, Obsidian, Stingray 128/3D, etc.).
+ The Quantum3D Obsidian3D-2 X-24 requires some special env. setting
+ under Linux (more information in the "Useful Glide Environment
+ Variables");
+
+ - The 3Dfx Glide library 2.3 or later for your OS (the 2.4 works fine).
+ The Voodoo2 requires the Glide library 2.51. The Glide 3.1 is not
+ compatible with the Glide 2.x so it doesn't work with the current
+ version of the driver;
+
+ - A compiler supported by the Glide library (Micro$oft VC++ (tested),
+ Watcom (tested), GCC for Linux (tested), etc.);
+
+ - It's nice to have two monitors - one for your normal graphics
+ card and one for your 3Dfx card. If something goes wrong with
+ an application using the 3Dfx hardware you can still see your
+ normal screen in order to recover.
+
+
+
+Tested on:
+----------
+ Windows 95 - David Bucciarelli
+ Windows NT - Henri Fousse
+ MS-DOS
+ Linux - Daryll Strauss, Brian Paul, David Bucciarelli
+ FreeBSD
+ BeOS - Duncan Wilcox
+ MacOS - Fazekas Miklos
+
+
+What is able to do ?
+--------------------
+
+ - It is able accelerate points, lines and polygon with flat
+ shading, gouraud shading, Z-buffer, texture mapping, blending, fog and
+ antialiasing (when possible). There is also the support for rendering
+ in a window with a slow trick for the Voodoo Graphics (available only
+ for Linux) and at full speed with the Voodoo Rush chipset.
+ Under Linux is also possible to switch on-the-fly between the fullscreen
+ and in-window rendering hack.
+ There is also the support for using more than one Voodoo Graphics in the
+ some application/PC (you can create one context for each board and use
+ multiple video outputs for driving monitors, videoprojectors or HMDs).
+ The driver is able to fallback to pure software rendering when afeature
+ isn't supported by the Voodoo hardware (however software rendering is
+ very slow compared to hardware supported rendering)
+
+
+
+How to compile:
+---------------
+
+Linux:
+------
+ Here are the basic steps for using the 3Dfx hardware with Mesa
+ on Linux:
+
+ - You'll need the Glide library and headers. Mesa expects:
+ /usr/local/glide/include/*.h // all the Glide headers
+ /usr/local/glide/lib/libglide2x.so
+
+ If your Glide libraries and headers are in a different directory
+ you'll have to modify the Mesa-config and mklib.glide files.
+
+ - Unpack the MesaLib-3.1.tar.gz and MesaDemos-3.1.tar.gz archives;
+
+ - If you're going to use a newer Mesa/Glide driver than v0.27 then
+ unpack the new driver archive over the Mesa directory.
+
+ - In the Mesa-3.1 directory type "make linux-glide"
+
+ - Compilation _should_ finish without errors;
+
+ - Set your LD_LIBRARY_PATH environment variable so that the
+ libglide2x.so and Mesa library files can be found. For example:
+ setenv LD_LIBRARY_PATH "/usr/local/glide/lib:/SOMEDIR/Mesa-3.1/lib"
+
+ - You'll have to run Glide-based programs as root or set the suid
+ bit on executables;
+
+ - Try a demo:
+ cd gdemos
+ su
+ setenv MESA_GLX_FX f
+ ./gears (hit ESC to exit)
+
+ - You can find the demos especially designed for the Voodoo driver in
+ in the Mesa-3.1/3Dfx/demos directory (type "make" in order to compile
+ everything).
+
+MacOS:
+------
+ Check the WEB page at http://valerie.inf.elte.hu/~boga/Mesa.html
+
+MS Windows:
+-----------
+
+ For the MSVC++:
+ - The glide2x.lib have to be in the default MSVC++ lib directory;
+
+ - The Glide headers have to be in the default MSVC++ include directory;
+
+ - You must have the vcvars32.bat script in your PATH;
+
+ - Go to the directory Mesa-3.1 and run the mesafx.bat;
+
+ - The script will compile everything (Mesa-3.1/lib/OpenGL32.{lib,dll},
+ Mesa-3.1/lib/GLU32.{lib,dll}, Mesa-3.1/lib/GLUT32.{lib,dll} and
+ Voodoo demos);
+
+ - At the end, you will be in the Mesa-3.1/3Dfx/demos directory;
+
+ - Try some demo (fire.exe, teapot.exe, etc.) in order to check if
+ everything is OK (you can use Alt-Tab or Ctrl-F9 to switch between
+ the Voodoo screen and the windows desktop);
+
+ - Remember to copy the Mesa OpenGL32.dll, GLU32.dll and GLUT32.dll in the
+ some directory were you run your Mesa based applications.
+
+ - I think that you can easy change the Makefile.fx files in order
+ to work with other kind of compilers;
+
+ - To discover how open the 3Dfx screen, read the sources under
+ the Mesa-3.1/3Dfx/demos directory. You can use the GLUT library or
+ the Diego Picciani's wgl emulator.
+
+ NOTE: the MSVC++ 5.0 optimizer is really buggy. Also if you install the
+ SP3, you could have some problem (you can disable optimization in order
+ solve these kind of problems).
+
+
+Doing more with Mesa & Linux Glide:
+-----------------------------------
+
+ The MESA_GLX_FX environment variable can be used to coax most
+ GLX-based programs into using Glide (and the __GLUT library
+ is GLX-based__).
+
+ Full-screen 3Dfx rendering:
+ ---------------------------
+
+ 1. Set the MESA_GLX_FX variable to "fullscreen":
+
+ ksh:
+ export MESA_GLX_FX = "fullscreen"
+ csh:
+ setenv MESA_GLX_FX fullscreen
+
+ 2. As root, run a GLX-based program (any GLUT demo on Linux).
+
+ 3. Be careful: once the 3Dfx screen appears you won't be able
+ to see the GLUT windows on your X display. This can make using
+ the mouse tricky! One solution is to hook up your 3Dfx card to
+ a second monitor. If you can do this then set these env vars
+ first:
+
+ setenv SST_VGA_PASS 1
+ setenv SST_NOSHUTDOWN
+
+ or for the Voodoo2:
+
+ setenv SSTV2_VGA_PASS 1
+ setenv SSTV2_NOSHUTDOWN
+
+ Rendering into an X window with the help of the Voodoo hardware:
+ ----------------------------------------------------------------
+
+ 1. Start your X server in 16 bpp mode (XFree86: startx -- -bpp 16)
+ in order to have the best performance and the best visual
+ quality. However you can use any visual depth supported by X.
+
+ 2. Set the following environment variables:
+ export MESA_GLX_FX="window" # to enable window rendering
+ export SST_VGA_PASS=1 # to stop video signal switching
+ export SST_NOSHUTDOWN=1 # to stop video signal switching
+ OR
+ setenv MESA_GLX_FX window
+ setenv SST_VGA_PASS 1
+ setenv SST_NOSHUTDOWN 1
+
+ (the Voodoo2 requires to use "SSTV2_" instead "SST_").
+
+ 3. As root, try running a GLX-based program
+
+ How does it work? We use the 3Dfx hardware to do rendering then
+ copy the image from the 3Dfx frame buffer into an X window when
+ the SwapBuffers() function is called. The problem with this
+ idea is it's slow. The image must be copied from the 3Dfx frame
+ buffer to main memory then copied into the X window (and when the X
+ visual depth doesn't match the Voodoo framebufffer bit per pixel, it
+ is required also a pixel format translation).
+
+ NOTE: the in-window rendering feature only works with double-buffering.
+
+
+ On the fly switching between in window rendering and full screen rendering
+ --------------------------------------------------------------------------
+
+ The Mesa 2.6 has introduced the capability of switching
+ on-the-fly between the fullscreen/fullspeed rendering and the in-window
+ hack and vice versa. The on-the-fly switching requires a direct support
+ by the application but it is really easy to add. You have to start
+ your X server in 16 bpp mode and to add the following lines to your
+ application:
+
+ #if defined(FX) && define(XMESA)
+ #include
+
+ static int fullscreen=1;
+ #endif
+
+ ...
+
+ /* In the GLUT keyboard event callback */
+
+ #if defined(FX) && !define(WIN32)
+ case ' ':
+ fullscreen=(!fullscreen);
+ XMesaSetFXmode(fullscreen ? XMESA_FX_FULLSCREEN : XMESA_FX_WINDOW);
+ break;
+ #endif
+ ...
+
+ See the 3Dfx/demos/tunnel.c program
+ for an example. You have to set the -DXMESA flag in the Makefile's COPTS
+ to enable it.
+
+ Rendering into an X window with the X11 software driver:
+ --------------------------------------------------------
+
+ Set the MESA_GLX_FX variable to "disable" your GLX-based program will use
+ the X11 software driver (the 3Dfx hardware isn't used at all).
+
+
+
+Useful Glide Environment Variables:
+-----------------------------------
+
+ - To disable the 3Dfx logo, set the FX_GLIDE_NO_SPLASH variable.
+
+ - To disable video signal switching:
+ setenv SST_VGA_PASS 1
+ setenv SST_NOSHUTDOWN
+ or for the Voodoo2:
+ setenv SSTV2_VGA_PASS 1
+ setenv SSTV2_NOSHUTDOWN
+
+ - To set the default screen refresh rate:
+ setenv SST_SCREENREFRESH=75
+
+ the supported values are 60, 70, 72, 75, 80, 85, 90, 100, 120.
+
+ - To force the Mesa library to swap buffers as fast as possible,
+ without any vertical blanking synchronization (useful for benchmarks):
+ setenv FX_GLIDE_SWAPINTERVAL 0
+ setenv SST_SWAP_EN_WAIT_ON_VIDSYNC 0
+
+ - You can slight improve the performances of your Voodoo1 board with
+ the following env. var.:
+ setenv SST_FASTMEM 1
+ setenv SST_PCIRD 1
+ setenv SST_GRXCLK 57
+
+ (don't use this setting with the Quantum3D 100SB or with any other
+ SLI configuration: it will hang everything !).
+ The following setting can be used with the Voodoo2:
+ setenv SSTV2_FASTMEM_RAS_READS=1
+ setenv SSTV2_FASTPCIRD=1
+ setenv SSTV2_GRXCLK=95
+
+ - The Quantum3D Obsidian3D-2 X-24 requires some special env. setting
+ in order to work under Linux:
+
+ export SSTV2_FT_CLKDEL=5
+ export SSTV2_TF0_CLKDEL=7
+ export SSTV2_TF1_CLKDEL=7
+ export SSTV2_TF2_CLKDEL=7
+ export SSTV2_SLIM_VIN_CLKDEL=3
+ export SSTV2_SLIM_VOUT_CLKDEL=2
+ export SSTV2_SLIS_VIN_CLKDEL=3
+ export SSTV2_SLIS_VOUT_CLKDEL=2
+
+ (Thanks to Phil Ross for this trick).
+
+
+
+
+The Mesa/Voodoo Environment Variables:
+--------------------------------------
+
+ - Only for Windows/Voodoo Rush users, if you define the
+ env. var. MESA_WGL_FX:
+ export MESA_WGL_FX=fullscreen
+ you will get fullscreen rendering;
+
+ - Only for Windows/Voodoo Rush users, if you define the
+ env. var. MESA_WGL_FX:
+ export MESA_WGL_FX=window
+ you will get window rendering (default value);
+
+ - Only for Linux users, you can find more informations about
+ the env. var. MESA_GLX_FX in the "Doing more with Mesa & Linux Glide"
+ section;
+
+ - If you define the env. var. MESA_FX_SWAP_PENDING:
+ export MESA_FX_SWAP_PENDING=4
+ you will able to set the maximum number of swapbuffers
+ commands in the Voodoo FIFO after a swapbuffer (default value: 2);
+
+ - If you define the env. var. MESA_FX_INFO:
+ export MESA_FX_INFO=1
+ you will get some useful statistic.
+
+ - If you define the env. var. MESA_FX_NO_SIGNALS:
+ export MESA_FX_NO_SIGNALS=1
+ Mesa/FX will not install atexit() or signal() handlers.
+
+
+
+Know BUGS and Problems:
+-----------------------
+
+ - fog doesn't work in the right way when using the glDepthRange() function;
+
+ - Maximum texture size: 256x256 (this is an hardware limit);
+
+ - Texture border aren't yet supported;
+
+ - A GL_BLEND in a glTexEnv() is not supported (it is an hardware limit);
+
+ - Use the glBindTexture extension (standard in OpenGL 1.1) for texture
+ mapping (the old way: glTexImage inside a display list, download
+ the texture map each time that you call the display list !!!);
+
+ - Stencil buffer and Accumulation buffer are emulated in software (they are not
+ directly supported by the Hardware);
+
+ - Color index mode not implemented (this is an hardware limit);
+
+ - Thre is an know bug in the Linux Glide library so the in-window-rendering hack
+ and any other operations that requires to read the Voodoo frame buffer
+ (like the accumulation buffer support) doesn't work on Voodoo SLI cards.
+
+ - The driver switch to pure software (_slow_) rendering when:
+
+ - Stencil enabled;
+ - Using the Accumulation buffer;
+ - Blend enabled and blend equation != GL_FUNC_ADD_EXT;
+ - Color logic operation enabled and color logic operation != GL_COPY;
+ - Using GL_SEPARATE_SPECULAR_COLOR;
+ - The four values of glColorMask() aren't the some;
+ - Texture 1D or 3D enabled;
+ - Texture function is GL_BLEND;
+ - Using the Multitexture extension with Voodoo cards with only one TMU;
+ - Using the Multitexture extension with Voodoo cards with more than
+ one TMU, and texture function isn't GL_MODULATE;
+ - Point size is != 1.0 or point params vector != (1.0,0.0,0.0);
+ - Line width != 1.0 or using stipple lines.
+ - Using polygon offset or stipple polygons;
+
+ NOTE: this is list is not yet complete.
+
+
+Hints and Special Features:
+---------------------------
+
+ - Under Linux and with a Voodoo Graphics board, you can use
+ XMesaSetFXmode(XMESA_FX_FULLSCREEN or XMESA_FX_WINDOW) in order to
+ switch on the fly between fullscreen rendering and the in-window-rendering
+ hack.
+
+ - The driver is able to use all the texture memory available: 2/4MB on
+ Voodoo1 boards and 8MB (!) on high-end Voodoo1 and Voodoo2 boards.
+
+ - Trilinear filtering is fully supported on Voodoo boards with two TMUs
+ (high-end Voodoo1 boards and Voodoo2 boards). When only one TMU is
+ available the driver fallback to bilinear filter also if you ask
+ for trilinear filtering.
+
+ - The Voodoo driver support multiple Voodoo Graphics boards in the
+ some PC. Using this feature, you can write applications that use
+ multiple monitors, videoprojectors or HMDs for the output. See
+ Mesa-3.1/3Dfx/demos/tunnel2.c for an example of how setup one
+ context for each board.
+
+ - The v0.19 introduces a new powerful texture memory manager: the
+ texture memory is used as a cache of the set of all defined texture
+ maps. You can now define several MBs of texture maps also with a 2MB
+ of texture memory (the texture memory manager will do automatically
+ all the swap out/swap in
+ texture memory work). The new texture memory manager has also
+ solved a lot of other bugs/no specs compliance/problems
+ related to the texture memory usage.
+
+ - Use triangles and quads strip: they are a LOT faster than sparse
+ triangles and quads.
+
+ - The Voodoo driver supports the GL_EXT_paletted_texture. it works
+ only with GL_COLOR_INDEX8_EXT, GL_RGBA palettes and the alpha value
+ is ignored because this is a limitation of the current Glide
+ version and of the Voodoo hardware. See Mesa-3.1/3Dfx/demos/paltex.c for
+ a demo of this extension.
+
+ - The Voodoo driver directly supports 3Dfx Global Palette extension.
+ It was written for GLQuake and I think that it isn't a good idea
+ to use this extension for any other purpose (it is a trick). See
+ Mesa-3.1/3Dfx/demos/glbpaltex.c for a demo of this extension.
+
+ - The Voodoo driver chooses the screen resolution according to the
+ requested window size. If you open a 640x480 window, you will get
+ a 640x480 screen resolution, if you open a 800x600 window, you
+ will get a 800x600 screen resolution, etc.
+ Most GLUT demos support the '-geometry' option, so you can choose
+ the screen resolution: 'tunnel -geometry 800x600'.
+ Clearly, you Voodoo board must have enough framebuffer RAM (otherwise
+ the window creation will fail).
+
+ - The glGetString(GL_RENDERER) returns more information
+ about the hardware configuration: "Mesa Glide
+ CARD/ FB/
+ TM/ TMU/"
+ where: CARD is the card used for the current context,
+ FB is the number of MB for the framebuffer,
+ TM is the number of MB for the texture memory,
+ TMU is the number of TMU. You can try to run
+ Mesa/demos/glinfo in order to have an example of the output.

+
+FAQ:
+----
+
+For a complete FAQ check the Bernd Kreimeier's Linux 3Dfx HOWTO
+available at http://www.gamers.org/dEngine/xf3D (it includes also
+a lot of informations not strictly related to Linux, so it can be
+useful also if you don't use Linux)
+
+1. What is 3Dfx?
+
+3Dfx Interactive, Inc. is the company which builds the VooDoo 3-D graphics
+chipset (and others) used in popular PC cards such as the Diamond Monster 3D
+and the Orchid Righteous 3D (more informations at http://www.3dfx.com).
+
+
+2. What is Glide?
+
+Glide is a "thin" programming interface for the 3Dfx hardware. It was
+originally written for Windows/Intel but has been ported to Linux/Intel
+by Daryll Strauss.
+
+3Dfx, Inc. should be applauded for allowing the Linux version of Glide
+to be written.
+
+You can directly program with the Glide library if you wish. You can
+obtain Glide from the "Developer" section of the 3Dfx website: www.3dfx.com
+There's a Linux/Glide newsgroup at news://news.3dfx.com/3dfx.glide.linux
+
+
+3. What is fxmesa?
+
+"fxmesa" is the name of the Mesa device driver for the 3Dfx Glide library.
+It was written by David Bucciarelli and others. It works on both Linux
+and Windows. Basically, it allows you to write and run OpenGL-style programs
+on the 3Dfx hardware.
+
+
+4. What is GLQuake?
+
+Quake is a very popular game from id software, Inc. See www.idsoftware.com
+GLQuake is a version of Quake written for OpenGL. There is now a Linux
+version of GLQuake with works with the Mesa/3Dfx/Glide combo.
+
+Here's what you need to run GLQuake on Linux:
+ PC with 100MHz Pentium or better
+ a 3Dfx-based card
+ Mesa 3.1 libraries: libMesaGL.so libMesaGLU.so
+ Glide 2.4 libraries: libglide2x.so libtexus.so
+ GLQuake for Linux.
+
+Also, the windows version of GLQuake works fine with the Mesa OpenGL32.dll,
+you have only to copy the Mesa-3.1/lib/OpenGL32.dll in the GLQuake directory
+in order to test 'MesaQuake'.
+
+
+5. What is GLUT?
+
+GLUT is Mark Kilgard's OpenGL Utility Toolkit. It provides an API for
+writing portable OpenGL programs with support for multiple windows, pop-
+up menus, event handling, etc.
+
+Check the Mark's home page for more informations (http://reality.sgi.com/mjk_asd).
+
+Every OpenGL programmer should check out GLUT.
+
+GLUT on Linux uses GLX.
+
+
+6. What is GLX?
+
+GLX is the OpenGL extension to the X Window System. I defines both a
+programming API (glX*() functions) and a network protocol. Mesa implements
+an emulation of GLX on Linux. A real GLX implementation would requires
+hooks into the X server. The 3Dfx hardware can be used with GLX-based
+programs via the MESA_GLX_FX environment variable.
+
+
+7. Is the Voodoo driver able to use the 4Mb texture memory of
+the Pure3D boards ?
+
+Yes, the Voodoo driver v0.20 includes the support for Voodoo
+Graphics boards with more than 2Mb of texture memory.
+
+
+8. Do the Voodoo driver support the Voodoo Rush under Windows ?
+
+Yes, Diego Picciani has developed the support for the Voodoo
+Rush but David Bucciarelli has a Pure3D and a Monster3D and Brian Paul
+has a Monster3D, so the new versions of the Mesa/Voodoo sometime are
+not tested with the Voodoo Rush.
+
+
+9. Do the Voodoo driver support the Voodoo Rush under Linux ?
+
+No because the Linux Glide doesn't (yet) support the Voodoo Rush.
+
+
+10. Can I sell my Mesa/Voodoo based software and include
+a binary copy of the Mesa in order to make the software
+working out of the box ?
+
+Yes.
+
+
+11. Which is the best make target for compiling the Mesa for
+Linux GLQuake ('make linux-glide', 'make linux-386-glide', etc.) ?
+
+'make linux-386-opt-glide' for Voodoo1 and 'make linux-386-opt-V2-glide'
+for Voodoo2 boards because it doesn't include the '-fPIC'
+option (4-5% faster).
+
+
+12. Can I use a Mesa compiled with a 'make linux-386-opt-V2-glide'
+for my applications/programs/demos ?
+
+Yes, there is only one constrain: you can't run two Mesa applications
+at the some time. This isn't a big issue with the today Voodoo Graphics.
+

+AMIGA AMIWIN PORT of MESA: THE OPENGL SOFTWARE EMULATION
+========================================================
+Port by Victor Ng-Thow-Hing (victorng@dgp.toronto.edu)
+Original Author (Brian Paul (brianp@ssec.wisc.edu)
+
+Dec.1 , 1995: Port of release Mesa 1.2.5
+ - Modifications made to minimize changes to Mesa distribution.
+
+Nov.25, 1995: Port of release Mesa 1.2.4
+
+
+HISTORY
+=======
+As a 3D graphics progammer, I was increasingly frustrated to see OpenGL
+appearing on so many platforms EXCEPT the Amiga. Up to now, the task
+of porting OpenGL directly from native Amiga drawing routines seemed like
+a daunting task. However, two important events made this port possible.
+
+First of all, Brian Paul wrote Mesa, the OpenGL software emulator that
+can be found on many platforms - except the Amiga and Atari (who cares
+about the latter!). This was pretty ironic considering that Mesa was
+originally prototyped on an Amiga! The second great event was when
+Holger Kruse developed AmiWin, the X11R6 server for the Amiga (definitely
+register for this great piece of software) and released a development kit
+so one could compile X programs with SAS/C.
+
+Since Mesa had X routines as its primitive drawing operations, this made
+a marriage of Mesa and Amiwin feasible. I copied over the sources from
+an ftp site, played with the code, wrote some Smakefiles, and voila,
+I had OpenGL programs displaying on my Amiga.
+
+Although the speed is nothing to be impressed about, this port can be
+potentially useful to those who want to quickly test their code in
+wireframe or perhaps learn more about programming with the OpenGL API.
+
+I hope Amiga developers will continue to write excellent software for
+their machine, especially more X clients for Amiwin. If you have any
+solutions so some of my problems in the porting notes, please send me
+some email!
+
+See you around,
+Vic.
+
+HOW TO CREATE THE LIBRARIES AND SAMPLE CODE
+===========================================
+
+Just run the shell script mklib.amiwin in the mesa directory. This will
+make all the libraries and copy them into the mesa/lib directory. If you
+don't want to compile everything, just go to the desired directory and
+type smake in that directory.
+
+Change any of the variables in the smakefiles as necessary. You will REQUIRE
+the Amiwin development kit to compile these libraries since you need X11.LIB
+and the shareable X libraries. Some examples require the AmiTCP4.0
+net.lib static link library and related header files for unix related
+header files and functions like sleep().
+
+HOW TO USE THE MESA LIBRARIES
+=============================
+
+Study the Smakefiles in the demos, samples and book directories for the
+proper SAS/C options and linkable libraries to use. Basically aux calls
+require Mesaaux.LIB, gl calls require MesaGL.LIB, glu calls MesaGLU.LIB,
+tk calls Mesatk.LIB. There is a preliminary port of MesaGLUT.LIB toolkit
+available in the lib directory with the other Mesa libraries. However,
+it seems to cause crashes on some of the sample code. Someone else may want
+to attempt a more stable port.
+
+PORTING NOTES TO AMIWIN
+=======================
+
+My strategy of porting was to leave as much of the code untouched as
+possible. I surrounded any amiga specific changes with
+#ifdef AMIWIN ... #endif or #ifndef AMIWIN ... #endif preprocessor
+symbols. The code was ported on an Amiga 2000, with Fusion 40 accelerator
+and a Picasso II graphics card. The SAS/C 6.56 compiler was used, with
+the AmiWin 2.16 X development kit.
+
+All compilations were done for a 68040 CPU with 68882 math coprocessor for
+maximum speed. Please edit the smakefile for other compilers.
+I wrote smakefiles for the directories I ported. I omitted the Windows
+and Widgets directories. The former is for MS Windows and the latter
+requires Motif, which is not easily available for the Amiga.
+
+Here are the changes I did per directory:

+
+ Mesa / BeOS Information
+
+
+
+* Introduction
+
+Brian Paul added in Mesa 3.1 a driver for BeOS R4.5 operating system.
+This driver implements a clone of the BGLView class. This class,
+derived from BView, allows OpenGL rendering into any BeOS window. His
+driver was updated in Mesa 4.1 and again in version 6.1 by Philippe
+Houdoin, who's maintaining this driver since.
+
+Any application which uses the BGLView should be able to use Mesa
+instead of Be's OpenGL without changing any code.
+
+Since Be's OpenGL implementation (as of R5) is basically just the
+SGI sample implementation, it's pretty slow. You'll see that Mesa
+is considerably faster.
+
+
+* Source Code
+
+The source code for the driver is in src/mesa/drivers/beos/ directory.
+It's not 100% finished at this time but many GLUT-based demos are
+working. No optimizations have been made at this time.
+
+
+* Compiling
+
+Since Mesa 6.x, it can be build under BeOS with both the R5 builtin gcc version
+or more recent gcc versions available for BeOS, like this gcc version 2.95.3 for BeOS
+you can find at http://www.bebits.com/app/2157.
+Anyway, keep in mind that to take full advantage of Mesa x86 optimizations, you better
+want to use gcc 2.95.3 or sooner versions...
+
+To build Mesa-powered BeOS libGL.so version, open an Terminal window,
+move to Mesa root folder and type this command:
+
+$ make beos
+
+Note that the "beos" argument is only needed the first time to setup build config.
+Next times, typing "make" will be enough.
+
+When it finishes the Mesa based libGL.so library for
+BeOS will be in the lib/ directory, along libglut.so library.
+Several demo/test programs should have been build too under progs/* folders.
+If it stop when building one of the progs/* programs, you may want to ignore it
+and force make to move on next target by adding the -k make option:
+
+$ cd progs
+$ make -k
+
+To install it as Be's default libGL.so replacement, put it in your
+/boot/home/config/lib/ directory. All your GL/GLUT apps will use
+the Mesa based then.
+
+By default, it build a non-debug version library.
+The x86 (MMX, SSE and 3DNOW) optimizations are also supported for x86 target.
+For PowerPC BeOS flavor, sorry, Mesa don't have ppc (Altivec) optimizations
+yet.
+
+To build a DEBUG version, type instead this :
+
+$ DEBUG=1 make
+
+
+* Example Programs
+
+Look under progs/beos/ for some BGLView-based programs.
+You should find under progs/samples and progs/redbook directories GLUT-based programs too.
+They all should have been compiled along with the Mesa library.
+
+
+* GLUT
+
+A beta version of GLUT 3.7 port for BeOS, made by Jake Hamby, can be found at
+http://anobject.com/jehamby/Code/Glut-3.7-x86.zip.
+This is the version currently included in Mesa source code, and
+build in lib/libglut.so.
+
+A previous 3.5 version of this GLUT BeOS port used to be available at
+http://home.beoscentral.com/jehamby/Glut-3.5-x86.zip.
+
+They're special versions of GLUT for the BeOS platform. I don't
+believe Mark Kilgard's normal GLUT distribution includes BeOS
+support.
+
+
+* Special Features
+
+Mesa's implementation of the BGLView class has an extra member
+function: CopySubBufferMESA(). It basically works like SwapBuffers()
+but it only copies a sub region from the back buffer to the front
+buffer. This is a useful optimization for some applications.
+If you use this method in your code be sure that you check at runtime
+that you're actually using Mesa (with glGetString) so you don't
+cause a fatal error when running with Be's OpenGL.
+
+
+* Work Left To Do
+
+- BDirectWindow single buffering support is not implemented yet.
+- Color index mode is not implemented yet.
+- Reading pixels from the front buffer not implemented yet.
+- There is also a BGLScreen class in BeOS for full-screen OpenGL rendering.
+ This should also be implemented for Mesa.
+- Multiple renderers add-ons support, first step toward hardware acceleration
+ support.
+
+* Other contributors to this BeOS port
+
+Jake Hamby jhamby anobject com
+Marcin Konicki ahwayakchih neoni net
+Francois Revol revol free fr
+Nathan Whitehorn nathanw uchicago edu
+
+
+* Older BeOS Driver
+
+Mesa 2.6 had an earlier BeOS driver. It was based on Mesa's Off-screen
+rendering interface, not BGLView. If you're interested in the older
+driver you should get Mesa 2.6.
+
+
+* BeOS and Glide
+
+Mesa 3.0 supported the 3Dfx/Glide library on Beos. Download Mesa 3.0
+if interested. Ideally, the 3Dfx/Glide support should be updated to
+work with the new Mesa 3.1 BGLView implementation.
+
+The Glide library hasn't been updated for BeOS R4 and newer, to my knowledge,
+as of February, 1999.

+
+ Mesa Cygwin/X11 Information
+
+
+WARNING
+=======
+
+If you installed X11 (packages xorg-x11-devel and xorg-x11-bin-dlls ) with the
+latest setup.exe from Cygwin the GL (Mesa) libraries and include are already
+installed in /usr/X11R6.
+
+The following will explain how to "replace" them.
+
+Installation
+============
+
+How to compile Mesa on Cygwin/X11 systems:
+
+1. Shared libs:
+ type 'make cygwin-sl'.
+
+ When finished, the Mesa DLL will be in the Mesa-x.y/lib/ and
+ Mesa-x.y/bin directories.
+
+
+2. Static libs:
+ type 'make cygwin-static'.
+ When finished, the Mesa libraries will be in the Mesa-x.y/lib/ directory.
+
+Header and library files:
+ After you've compiled Mesa and tried the demos I recommend the following
+ procedure for "installing" Mesa.
+
+ Copy the Mesa include/GL directory to /usr/X11R6/include:
+ cp -a include/GL /usr/X11R6/include
+
+ Copy the Mesa library files to /usr/X11R6/lib:
+ cp -a lib/* /usr/X11R6ocal/lib
+
+ Copy the Mesa bin files (used by the DLL stuff) to /usr/X11R6/bin:
+ cp -a lib/cyg* /usr/X11R6/bin
+
+Xt/Motif widgets:
+ If you want to use Mesa or OpenGL in your Xt/Motif program you can build
+ the widgets found in either the widgets-mesa or widgets-sgi directories.
+ The former were written for Mesa and the later are the original SGI
+ widgets. Look in those directories for more information.
+ For the Motif widgets you must have downloaded the lesstif package.
+
+
+Using the library
+=================
+
+Configuration options:
+ The file src/mesa/main/config.h has many parameters which you can adjust
+ such as maximum number of lights, clipping planes, maximum texture size,
+ etc. In particular, you may want to change DEPTH_BITS from 16 to 32
+ if a 16-bit depth buffer isn't precise enough for your application.
+
+
+Shared libraries:
+ If you compile shared libraries (Win32 DLLS) you may have to set an
+ environment variable to specify where the Mesa libraries are located.
+ Set the PATH variable to include /your-dir/Mesa-2.6/bin.
+ Otherwise, when you try to run a demo it may fail with a message saying
+ that one or more DLL couldn't be found.
+
+
+Xt/Motif Widgets:
+ Two versions of the Xt/Motif OpenGL drawing area widgets are included:
+
+ widgets-sgi/ SGI's stock widgets
+ widgets-mesa/ Mesa-tuned widgets
+
+ Look in those directories for details
+
+
+Togl:
+ Togl is an OpenGL/Mesa widget for Tcl/Tk.
+ See http://togl.sourceforge.net for more information.
+
+
+
+X Display Modes:
+ Mesa supports RGB(A) rendering into almost any X visual type and depth.
+
+ The glXChooseVisual function tries its best to pick an appropriate visual
+ for the given attribute list. However, if this doesn't suit your needs
+ you can force Mesa to use any X visual you want (any supported by your
+ X server that is) by setting the MESA_RGB_VISUAL and MESA_CI_VISUAL
+ environment variables. When an RGB visual is requested, glXChooseVisual
+ will first look if the MESA_RGB_VISUAL variable is defined. If so, it
+ will try to use the specified visual. Similarly, when a color index
+ visual is requested, glXChooseVisual will look for the MESA_CI_VISUAL
+ variable.
+
+ The format of accepted values is:
+ Here are some examples:
+
+ using the C-shell:
+ % setenv MESA_RGB_VISUAL "TrueColor 8" // 8-bit TrueColor
+ % setenv MESA_CI_VISUAL "PseudoColor 12" // 12-bit PseudoColor
+ % setenv MESA_RGB_VISUAL "PseudoColor 8" // 8-bit PseudoColor
+
+ using the KornShell:
+ $ export MESA_RGB_VISUAL="TrueColor 8"
+ $ export MESA_CI_VISUAL="PseudoColor 12"
+ $ export MESA_RGB_VISUAL="PseudoColor 8"
+
+
+Double buffering:
+ Mesa can use either an X Pixmap or XImage as the backbuffer when in
+ double buffer mode. Using GLX, the default is to use an XImage. The
+ MESA_BACK_BUFFER environment variable can override this. The valid
+ values for MESA_BACK_BUFFER are: Pixmap and XImage (only the first
+ letter is checked, case doesn't matter).
+
+ A pixmap is faster when drawing simple lines and polygons while an
+ XImage is faster when Mesa has to do pixel-by-pixel rendering. If you
+ need depth buffering the XImage will almost surely be faster. Exper-
+ iment with the MESA_BACK_BUFFER variable to see which is faster for
+ your application.
+
+
+Colormaps:
+ When using Mesa directly or with GLX, it's up to the application writer
+ to create a window with an appropriate colormap. The aux, tk, and GLUT
+ toolkits try to minimize colormap "flashing" by sharing colormaps when
+ possible. Specifically, if the visual and depth of the window matches
+ that of the root window, the root window's colormap will be shared by
+ the Mesa window. Otherwise, a new, private colormap will be allocated.
+
+ When sharing the root colormap, Mesa may be unable to allocate the colors
+ it needs, resulting in poor color quality. This can happen when a
+ large number of colorcells in the root colormap are already allocated.
+ To prevent colormap sharing in aux, tk and GLUT, define the environment
+ variable MESA_PRIVATE_CMAP. The value isn't significant.
+
+
+Gamma correction:
+ To compensate for the nonlinear relationship between pixel values
+ and displayed intensities, there is a gamma correction feature in
+ Mesa. Some systems, such as Silicon Graphics, support gamma
+ correction in hardware (man gamma) so you won't need to use Mesa's
+ gamma facility. Other systems, however, may need gamma adjustment
+ to produce images which look correct. If in the past you thought
+ Mesa's images were too dim, read on.
+
+ Gamma correction is controlled with the MESA_GAMMA environment
+ variable. Its value is of the form "Gr Gg Gb" or just "G" where
+ Gr is the red gamma value, Gg is the green gamma value, Gb is the
+ blue gamma value and G is one gamma value to use for all three
+ channels. Each value is a positive real number typically in the
+ range 1.0 to 2.5. The defaults are all 1.0, effectively disabling
+ gamma correction. Examples using csh:
+
+ % setenv MESA_GAMMA "2.3 2.2 2.4" // separate R,G,B values
+ % setenv MESA_GAMMA "2.0" // same gamma for R,G,B
+
+ The demos/gamma.c program may help you to determine reasonable gamma
+ value for your display. With correct gamma values, the color intensities
+ displayed in the top row (drawn by dithering) should nearly match those
+ in the bottom row (drawn as grays).
+
+ Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well
+ on HP displays using the HP-ColorRecovery technology.
+
+ Mesa implements gamma correction with a lookup table which translates
+ a "linear" pixel value to a gamma-corrected pixel value. There is a
+ small performance penalty. Gamma correction only works in RGB mode.
+ Also be aware that pixel values read back from the frame buffer will
+ not be "un-corrected" so glReadPixels may not return the same data
+ drawn with glDrawPixels.
+
+ For more information about gamma correction see:
+ http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html
+
+
+Overlay Planes
+
+ Overlay planes in the frame buffer are supported by Mesa but require
+ hardware and X server support. To determine if your X server has
+ overlay support you can test for the SERVER_OVERLAY_VISUALS property:
+
+ xprop -root | grep SERVER_OVERLAY_VISUALS
+
+
+HPCR glClear(GL_COLOR_BUFFER_BIT) dithering
+
+ If you set the MESA_HPCR_CLEAR environment variable then dithering
+ will be used when clearing the color buffer. This is only applicable
+ to HP systems with the HPCR (Color Recovery) system.
+
+
+Extensions
+==========
+ There are three Mesa-specific GLX extensions at this time.
+
+ GLX_MESA_pixmap_colormap
+
+ This extension adds the GLX function:
+
+ GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
+ Pixmap pixmap, Colormap cmap )
+
+ It is an alternative to the standard glXCreateGLXPixmap() function.
+ Since Mesa supports RGB rendering into any X visual, not just True-
+ Color or DirectColor, Mesa needs colormap information to convert RGB
+ values into pixel values. An X window carries this information but a
+ pixmap does not. This function associates a colormap to a GLX pixmap.
+ See the xdemos/glxpixmap.c file for an example of how to use this
+ extension.
+
+ GLX_MESA_release_buffers
+
+ Mesa associates a set of ancillary (depth, accumulation, stencil and
+ alpha) buffers with each X window it draws into. These ancillary
+ buffers are allocated for each X window the first time the X window
+ is passed to glXMakeCurrent(). Mesa, however, can't detect when an
+ X window has been destroyed in order to free the ancillary buffers.
+
+ The best it can do is to check for recently destroyed windows whenever
+ the client calls the glXCreateContext() or glXDestroyContext()
+ functions. This may not be sufficient in all situations though.
+
+ The GLX_MESA_release_buffers extension allows a client to explicitly
+ deallocate the ancillary buffers by calling glxReleaseBuffersMESA()
+ just before an X window is destroyed. For example:
+
+ #ifdef GLX_MESA_release_buffers
+ glXReleaseBuffersMESA( dpy, window );
+ #endif
+ XDestroyWindow( dpy, window );
+
+ This extension is new in Mesa 2.0.
+
+ GLX_MESA_copy_sub_buffer
+
+ This extension adds the glXCopySubBufferMESA() function. It works
+ like glXSwapBuffers() but only copies a sub-region of the window
+ instead of the whole window.
+
+ This extension is new in Mesa version 2.6
+
+
+
+Summary of X-related environment variables:
+ MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode (X only)
+ MESA_CI_VISUAL - specifies the X visual and depth for CI mode (X only)
+ MESA_BACK_BUFFER - specifies how to implement the back color buffer (X only)
+ MESA_PRIVATE_CMAP - force aux/tk libraries to use private colormaps (X only)
+ MESA_GAMMA - gamma correction coefficients (X only)

+ Mesa 6.5 DOS/DJGPP Port v1.8
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+
+Description:
+~~~~~~~~~~~~
+
+Well, guess what... this is the DOS port of Mesa 6.5, for DJGPP fans... Whoa!
+The driver uses OSMesa to draw off screen, and then blits the buffer. This is
+not terribly efficient, and has some drawbacks, but saves maintenance costs.
+
+
+
+Legal:
+~~~~~~
+
+Mesa copyright applies.
+
+
+
+Installation:
+~~~~~~~~~~~~~
+
+Unzip and type:
+
+ make -f Makefile.DJ [OPTIONS...]
+
+Available options:
+
+ Environment variables:
+ CPU optimize for the given processor.
+ default = pentium
+ GLIDE path to Glide3 SDK; used with FX.
+ default = $(TOP)/glide3
+ FX=1 build for 3dfx Glide3. Note that this disables
+ compilation of most DMesa code and requires fxMesa.
+ As a consequence, you'll need the DJGPP Glide3
+ library to build any application.
+ default = no
+ X86=1 optimize for x86 (if possible, use MMX, SSE, 3DNow).
+ default = no
+
+ Targets:
+ all: build everything
+ libgl: build GL
+ libglu: build GLU
+ libglut: build GLUT
+ clean: remove object files
+ realclean: remove all generated files
+
+
+
+Tested on:
+ Video card: Radeon 9500
+ DJGPP: djdev 2.04 + gcc v4.1.0 + make v3.80
+ OS: DOS, Win98SE, WinXP (using Videoport driver)
+
+
+
+FAQ:
+~~~~
+
+1. Compilation
+
+ Q) `make' barfs and exits because it cannot find some stupid file.
+ A) You need LFN support.
+ A) When compiling for Glide (FX=1), pay attention to Glide path.
+
+ Q) Libraries built OK, but linker complains about `vsnprintf' every time I
+ compile some demo.
+ A) Upgrade to DJGPP 2.04.
+ A) Add `vsnprintf.c' to the CORE_SOURCES in `src/Makefile.DJ' (untested!).
+ A) Patch `src/mesa/main/imports.c' with the following line:
+ #define vsnprintf(buf, max, fmt, arg) vsprintf(buf, fmt, arg)
+ This hack should be safe in 90% of the cases, but if anything goes wrong,
+ don't come back to me crying.
+
+ Q) `make' complains about DXE3 or something, yet it builds the libraries.
+ A) DXE3 refers to the DJGPP dynamic modules. You'll need either the latest
+ DJGPP distro, or download the separate package from my web page. Read the
+ DXE3 documentation on how to use them.
+ A) When compiling for Glide (FX=1), make sure `glide3x.dxe' can be found in
+ LD_LIBRARY_PATH (or top `lib' directory).
+
+2. Using Mesa for DJGPP
+
+ Q) Every test I tried crashes badly.
+ A) If you have compiled with SSE and you're running under plain DOS, you
+ have to disable SSE at run-time. See environment variables below.
+
+ Q) DMesa is so SLOOOW! The Win32 OpenGL performs so much better...
+ A) Is that a question? If you have a 3dfx Voodoo (any model), you're
+ lucky (check http://sourceforge.net/projects/glide for the DJGPP port).
+ If you haven't, sorry; everything is done in software.
+
+ Q) I tried to set refresh rate w/ DMesa, but without success.
+ A) Refresh rate control works only for VESA 3.0 and the 3dfx driver (in
+ which case FX_GLIDE_REFRESH will be overwritten if it is defined and
+ is not 0).
+
+ Q) I made a simple application and it does nothing. It exits right away. Not
+ even a blank screen.
+ A) Software drivers (VESA/VGA/NUL) must to be constructed as single-buffered
+ visuals. However, DMesaSwapBuffers must be called to get any output.
+ A) Another weird "feature" is that buffer width must be multiple of 8 (I'm a
+ lazy programmer and I found that the easiest way to keep buffer handling
+ at peak performance ;-).
+
+ Q) I'm getting a "bad font!" fatal error.
+ A) Always use GLUT_STROKE_* and GLUT_BITMAP_* constants when dealing with
+ GLUT fonts. If you're using `glut.dxe', then make sure GLUT_STROKE_* and
+ GLUT_BITMAP_* are mapped to integer constants, not to the actual font
+ address (same mechanism used for Win32 _DLL).
+
+ Q) What is NUL driver good for, if I don't get any output at all?
+ A) For debugging. The NUL driver is very much like OSMesa. Everything is
+ done just the same as VESA/VGA drivers, only it doesn't touch your video
+ hardware. You can query the actual buffer by issuing:
+ DMesaGetIntegerv(DMESA_GET_BUFFER_ADDR, &buffer);
+ and dump it to a file.
+
+ Q) How do I query for a list of available video modes to choose as a visual?
+ A) This is an ugly hack, for which I'm sure I'll burn in hell.
+ First, query for a list of modes:
+ n = DMesaGetIntegerv(DMESA_GET_VIDEO_MODES, NULL);
+ If `n' is strictly positive, you allocate an array of pointers to a given
+ struct (which is guaranteed to be extended only - not changed in future):
+ struct {
+ int xres, yres;
+ int bpp;
+ } **l = malloc(n * sizeof(void *));
+ Now pass the newly allocated buffer to fill in:
+ DMesaGetIntegerv(DMESA_GET_VIDEO_MODES, (GLint *)l);
+ And collect the info:
+ for (i = 0; i < n; i++) {
+ printf("%dx%d:%d\n", l[i]->xres, l[i]->yres, l[i]->bpp);
+ }
+
+ Q) The GLUT is incomplete.
+ A) See below.
+
+
+
+libGLUT (the toolkit):
+~~~~~~~~~~~~~~~~~~~~~~
+
+Well, this "skeletal" GLUT implementation was taken from AllegGL project and
+heavily changed. Thanks should go to Bernhard Tschirren, Mark Kilgard, Brian
+Paul and probably others (or probably not ;-). GLUT functionality will be
+extended only on an "as needed" basis.
+
+GLUT talks to hardware via PC_HW package which was put together from various
+pieces I wrote long time ago. It consists from the keyboard, mouse and timer
+drivers.
+
+My keyboard driver used only scancodes; as GLUT requires ASCII values for keys,
+I borrowed the translation tables (and maybe more) from Allegro -- many thanks
+to Shawn Hargreaves et co. Ctrl-Alt-Del (plus Ctrl-Alt-End, for Windows users)
+will shut down the GLUT engine unconditionally: it will raise SIGINT, which in
+turn will (hopefully) call the destructors, thus cleaning up your/my mess ;-)
+NB: since the DJGPP guys ensured signal handlers won't go beyond program's
+space (and since dynamic modules shall) the SIGINT can't be hooked (well, it
+can, but it is useless), therefore you must live with the 'Exiting due to
+signal SIGINT' message...
+
+The mouse driver is far from complete (lack of drawing, etc), but is enough to
+make almost all the demos work. Supports the CuteMouse WheelAPI.
+
+The timer is pretty versatile for it supports multiple timers with different
+frequencies. While not being the most accurate timer in the known universe, I
+think it's OK. Take this example: you have timer A with a very high rate, and
+then you have timer B with very low rate compared to A; now, A ticks OK, but
+timer B will probably loose precision!
+
+As an addition, stdout and stderr are redirected and dumped upon exit. This
+means that `printf' can be safely called during graphics. A bit of a hack, I
+know, because all messages come in bulk, but I think it's better than nothing.
+"Borrowed" from LIBRHUTI (Robert Hoehne).
+
+Window creating defaults: (0, 0, 300, 300), 16bpp. However, the video mode is
+chosen in such a way that first window will fit. If you need high resolution
+with small windows, set initial position far to the right (or way down); then
+you can move them back to any position right before the main loop.
+
+
+
+Environment variables:
+~~~~~~~~~~~~~~~~~~~~~~
+ DMESA_NULDRV - (any value) force NUL driver
+ GLUT_FPS - print frames/second statistics to stderr
+ MESA_NO_SSE - (any value) safe option under pure DOS
+ DMESA_GLUT_REFRESH - set vertical screen refresh rate (VESA3)
+ DMESA_GLUT_BPP - set default bits per pixel (VGA needs 8)
+ DMESA_GLUT_ALPHA - set default alpha bits (8)
+ DMESA_GLUT_DEPTH - set default depth bits (16)
+ DMESA_GLUT_STENCIL - set default stencil bits (8)
+ DMESA_GLUT_ACCUM - set default accum bits (16)
+

+Mesa 3.0 for LynxOS builds in the following way:
+
+make lynxos
+
+This will build all the libraries and demo applications. You should have
+around 400 megabytes free for everything since everything is done with
+static
+libraries.
+
+Before using this make file however, you should perform the following
+actions:
+0) cd to the Mesa-3.0 directory
+1) Copy the GL directory under the include directory to /usr/include.
+2) Copy the files in the lib directory to /lib.
+3) Make links so that the Mesa libraries look like ordinary OpenGL
+libraries
+in /lib. This is important for compatibility with other OpenGL apps. This
+is done as follows:
+
+cd /lib
+ln -s libMesaGL.a libGL.a
+ln -s libMesaGLU.a libGLU.a
+
+Mesa 3.0 includes the GLUT (GL Utility Toolkit) by default.
+The demo applications are done using this toolkit.
+
+Mesa makefiles for building their apps could be used as well, but the
+following one is much more concise. Note that the order of the X libraries
+is important to the linker so that all symbols get resolved correctly.
+Changing the order may result in having to list a library twice to make
+sure all linkages are made correctly.

+*******************************************************************************
+The Mingw port for Mesa 3-D Graphics Library was created August 30, 1998 by Paul Garceau.
+
+Updated January 13, 2000; June 3, 2005 -- Paul Garceau
+
+DISCLAIMER: I make this port of the Mesa 3-D Graphics Library as a service
+to the general public. I can, in no way support or make any guarantee that the
+build will work for your system.
+
+Acknowledgements:
+
+ Daniel Borca, whose work and commitment to maintaining the Mingw port of the Mesa 3-D Graphics Library has been, and will continue to be greatly appreciated by an overworked and underpaid developer such as myself.
+ Without the creative inspiration and personal commitment provided by Mumit Khan, Jan-Jaap Vanderhagen and Colin Peters, Mingw would never have existed. Acknowledgements also need to be given to all of the developers who have worked on Mingw, Mesa and Msys over the years.
+ Last, but certainly far from the least, Brian Paul, who has dedicated at least the last seven or eight years of his life to making Mesa 3-D Graphics Library what it is today and managing the development for all of those years.
+*********************************************************************************
+
+Greetings,
+
+ Feel free to modify or change things related to the Mingw build as you see fit, just remember that, the author of the current build may not be able to support any modifications you might want to make to the files which have been included for the build.
+
+Mesa core components are licensed under XFree-86 (for more on licensing of Mesa 3-D Graphics Library, check out the Mesa homepage (http://www.mesa3d.org).
+
+The Mingw generated libraries themselves are licensed under the GNU-LGPL license. Source code for Mingw can be found at http://www.mingw.org. For licensing terms on Mingw, please visit http://www.mingw.org.
+
+ It is recommended that you use the latest "stable" release of Mingw. "Candidates" are beta testing distributions for Mingw. Mingw is available at http://www.mingw.org.
+
+ This build has been tested under WinNT4/SP6. Win9x and WinNT5 remain untested by me. I have not tested any of the demos included with Mesa3d.
+
+Installation:
+
+ This readme assumes that you already have extracted the necessary files to a working directory/folder that Mingw can use to build the Mesa3D libraries and that you know where that directory/folder is located on your Windows system. If you have any questions about how to set things up properly which is specific to Mesa3D, the folks on the Mesa3D mailing lists (http://www.mesa3d.org) would probably be happy to assist you. Also you can probably ask anyone on the Mingw mailing lists for any questions specific to Mingw (http://www.mingw.org)
+
+Targets and Environment variables used for Mingw build:
+
+ Before going into the actual build of the libraries, here is a list of available targets for the make process:
+
+ "all" or "libgl" -- this target will build libopengl.a, a static library. It will not build the demos, etc.
+
+ clean -- this target will clean up most of the Mesa 3-D Graphics Library/object code from your hard drive.
+
+ realclean -- this target will clean up all of the Mesa 3D Graphics Library and the Mesa object code that it can find.
+
+ Environment Variables:
+
+ The environment variables are used to determine what sort of graphics driver support needs to be included in the finished Mesa 3-D Graphics Library.
+
+ GLIDE path to Glide3 SDK; used with FX.
+ default = $(TOP)/glide3
+ FX=1 build for 3dfx Glide3. Note that this disables
+ compilation of most WMesa code and requires fxMesa.
+ As a consequence, you'll need the Win32 Glide3
+ library to build any application.
+ default = no
+ ICD=1 build the installable client driver interface
+ (windows opengl driver interface)
+ default = no
+ X86=1 optimize for x86 (if possible, use MMX, SSE, 3DNow).
+ default = no
+
+
+Running the Build:
+
+ Launch Mingw.
+ From the Windows Command Prompt:
+ Set Environment Variables (as needed).
+ "cd" to your Mesa3D 'root' directory.
+ Enter "mingw32-make -f makefile.mgw
+
+ That's all there is to it.
+
+ Enjoy!
+
+ Paul G.

+====================
+
+Notice:
+ 1) The generated DLLs are *not* compatible with the ones built
+with the other compilers like VC8, especially for GLUT.
+
+ 2) Although more tests are needed, it can be used individually!
+
+ 3) You can set the options about whether using STDCALL to build MESA. The
+config file is \configs\config.mgw. The default setting is that:
+ ALL_USING_STDCALL = 1
+, which means using STDCALL to build MESA.
+
+ 4) Of course, you can MESA without using STDCALL,I like this:)
+The setting is :
+ ALL_USING_STDCALL = 0
+To do this, however, you must modify wingdi.h which is in MingW's include dir.
+For example, run:
+ notepad C:\MingW\include\wingdi.h
+, and delete all the lines where all the wgl*() functions are. Because they would
+be conflicted with the ones in \include\GL\mesa_wgl.h.

+
+====================
+Updated on 2007-7-22
+====================
+ I havn't thought that I would find a better way to solve my problems so soon.
+I changed the method in which the import-libs and DLLs are made. After this update,
+the DLLs of MESA are more optimized and more compatible.
+ It seems that there is no need to keep the building way of 'NO-STDCALL'.The
+way of USING_STDCALL is so nice! The file \configs\config.mgw is
+also not needed, and can be deleted safely!

+
+
+1. Requirements:
+ Mesa 3.0.
+ An SMP capable machine running Linux 2.x
+ libpthread installed on your machine.
+
+
+2. What does MITS stand for?
+ MITS stands for Mesa Internal Threading System. By adding
+ internal threading to Mesa it should be possible to improve
+ performance of OpenGL applications on SMP machines.
+
+
+3. Do applications have to be recoded to take advantage of MITS?
+ No. The threading is internal to Mesa and transparent to
+ applications.
+
+
+4. Will all applications benefit from the current implementation of MITS?
+ No. This implementation splits the processing of the vertex buffer
+ over two threads. There is a certain amount of overhead involved
+ with the thread synchronization and if there is not enough work
+ to be done the extra overhead outweighs any speedup from using
+ dual processors. You will not for example see any speedup when
+ running Quake because it uses GL_POLYGON and there is only one
+ polygon for each vertex buffer processed. Test results on a
+ dual 200 Mhz. Pentium Pro system show that one needs around
+ 100-200 vertices in the vertex buffer before any there is any
+ appreciable benefit from the threading.
+
+
+5. Are there any parameters that I can tune to try to improve performance.
+ Yes. You can try to vary the size of the vertex buffer which is
+ define in VB_MAX located in the file src/vb.h from your top level
+ Mesa distribution. The number needs to be a multiple of 12 and
+ the optimum value will probably depend on the capabilities of
+ your machine and the particular application you are running.
+
+
+6. Are there any ways I can modify the application to improve its
+ performance with the MITS?
+ Yes. Try to use as many vertices between each Begin/End pair
+ as possbile. This will reduce the thread synchronization
+ overhead.
+
+
+7. What sort of speedups can I expect?
+ On some benchmarks performance gains of up to 30% have been
+ observerd. Others may see no gain at all and in a few rare
+ cases even some degradation.
+
+
+8. What still needs to be done?
+ Lots of testing and benchmarking.
+ A portable implementation that works within the Mesa thread API.
+ Threading of additional areas of Mesa to improve performance
+ even more.
+
+
+
+Installation:
+
+ 1. This assumes that you already have a working Mesa 3.0 installation
+ from source.
+ 2. Place the tarball MITS.tar.gz in your top level Mesa directory.
+ 3. Unzip it and untar it. It will replace the following files in
+ your Mesa source tree so back them up if you want to save them.
+
+
+ README.MITS
+ Make-config
+ Makefile
+ mklib.glide
+ src/vbxform.c
+ src/vb.h
+
+ 4. Rebuild Mesa using the command
+
+ make linux-386-glide-mits

+The NeXT support has now been incorporated into the OpenStep support.
+You can build NeXT libraries simply by typing "make next", though before
+linking they will need to be ranlib'd by hand. For more information see

+ README for port of Mesa 3.x to XFree86 on OS/2 (X/2)
+ (as of 19990514)
+
+
+ Contents:
+
+ 1) Binary release
+ 2) Building from sources
+ 3) History
+ 4) Todo
+ 5) Mesa Home Page
+
+
+1) Binary release
+
+ Though the Mesa sources should build in a quite reasonable time even on
+ a 585 class machine a binary relase is available (check topic 4) for an URL)
+ This package includes:
+
+ - lib/MesaGL.dll, MesaGL.a
+ - lib/MesaGLU.dll, MesaGLU.a
+ - lib/glut.dll, glut.a
+ - include/GL/*.h
+
+ Installing this in your XFree86 tree will enable you to build and
+ run all applications compatible with Mesa (and the current DLL
+ interface, of course ;-)
+ As usual the OMF-style libraries can be created using emxomf.
+ (e.g. "emxomf foo.a" creates the foo.lib omf-style library).
+ The static libraries are rarely used and you have to rebuild
+ Mesa to get them. They're a supported target, so you get
+ them in a straightforward way (see below).
+
+ The testing of these libraries was limited to the supplied
+ demos/examples and a quite small number of third-party apps.
+ No warranty ... as usual ... ;-)
+
+
+2) Instructions to build Mesa 3.x for XFree86/OS2 from sources:
+
+ Except the official Mesa source distribution you need:
+ - a recent version of XFree86 (3.3.x or above) including
+ the programming libraries
+ - EMX 0.9c (0.9d might work, never checked)
+ - GNU make
+ - REXX (!)
+
+ The creation of the DLLs as well as of the static libraries
+ (if you want to have them) is handled in "mklib-emx.cmd",
+ a small REXX script. Perhaps not the best idea, but this
+ way it fits best in the scheme used to build libraries
+ on all platforms in Mesa 3.x.
+
+ To actually build the libraries and demos, check mklib-emx.cmd
+ and modify it as desired. Then type
+ make os2-x11
+ and wait for completion ;-)
+
+
+3) History
+
+ Initially Darren Abbott (abbott@hiwaay.net) ported Mesa versions 2.x
+ to XFree86 OS/2. This port might still be available from
+ http://fly.HiWAAY.net/~abbott/xfree86-os2/xfree86.html
+
+ The current port picked up things during the beta test for 3.0.
+ No major changes in the source were done. The build mechanism under OS/2
+ has been made very similar to other platforms (if you treat mklib-emx.cmd
+ as a "black box").
+ Advantage is that X/2 is now a valid target and all files are
+ integrated in the official source distribution.
+ Disadvantage is that this port (i.e. the DLLs' interface itself) is
+ definitly NOT COMPATIBLE to those of version 2.x.
+ It's uncertain whether this would be at all possible but since there
+ a _very_ few those apps it's not worth to find out anyway.
+ Also some libs (MesaTK, MesaAUX) are withdrawn from the Mesa distribution,
+ and accordingly from the OS/2 port.
+
+4) Todo
+
+ By now binary compatiblity is ensured by using the function names
+ as entry points instead of ordinals. This might cost performance and
+ is subject to change in future. In addition the supplied X86 assembler
+ source is not used yet.
+
+5) Mesa Home Page
+
+ You can get the source code and more information about Mesa from
+ http://www.mesa3d.org/
+
+ The OS/2 ports should be available from
+ http://r350.ee.ntu.edu.tw/~hcchu/os2/ports

+This is a port of the GL and GLU libraries to NeXT/Apple object
+orientated systems. As these systems have their own window handling
+systems we simply use the offscreen rendering capability of Mesa
+to generate bitmaps which may then be displayed by the application
+with a View as required. Example pieces of code may be found in the
+OpenStep directory.
+
+Sadly there are now a proliferation of different system that we need to
+support compilation for: The original NextStep system, The OpenStep
+system, the Rhapsody/Mac OS X system and also the windows implementations
+of the latter two systems. This version of the code has been compiled and
+tested under the following architectures:
+
+ NextStep 3.3
+ OpenStep 4.2
+ Rhapsody DR2
+ WebObjects for NT 3.5
+ WebObjects for NT 4.0
+
+All tests were done with Intel processors. Feedback on other systems would,
+however, be appreciated !
+
+On UNIX systems simply type "make openstep". Under Windows systems
+with WebObjects run the "win32-openstep.sh" script from within the Bourne
+shell provided with the development environment. In both cases this will
+build the libraries and place them into the "lib" directory. Some examples
+may be found in the OpenStep directory showing how to use the code in an
+actual application (MesaView) as well as some command line demos.
+
+The CC variable may be specified on the command line for doing such things
+as building FFAT libraries or using alternative compilers to the standard 'cc'
+e.g. make CC='cc -arch m68k -arch i386' openstep" will build the libraries
+with both intel and motorola architectures.

+ Info on using Mesa 3.0 with Linux Quake I and Quake II
+
+
+
+Disclaimer
+----------
+
+I am _not_ a Quake expert by any means. I pretty much only run it to
+test Mesa. There have been a lot of questions about Linux Quake and
+Mesa so I'm trying to provide some useful info here. If this file
+doesn't help you then you should look elsewhere for help. The Mesa
+mailing list or the news://news.3dfx.com/3dfx.linux.glide newsgroup
+might be good.
+
+Again, all the information I have is in this file. Please don't email
+me with questions.
+
+If you have information to contribute to this file please send it to
+me at brianp@elastic.avid.com
+
+
+
+Linux Quake
+-----------
+
+You can get Linux Quake from http://www.idsoftware.com/
+
+Quake I and II for Linux were tested with, and include, Mesa 2.6. You
+shouldn't have too many problems if you simply follow the instructions
+in the Quake distribution.
+
+
+
+RedHat 5.0 Linux problems
+-------------------------
+
+RedHat Linux 5.x uses the GNU C library ("glibc" or "libc6") whereas
+previous RedHat and other Linux distributions use "libc5" for its
+runtime C library.
+
+Linux Quake I and II were compiled for libc5. If you compile Mesa
+on a RedHat 5.x system the resulting libMesaGL.so file will not work
+with Linux Quake because of the different C runtime libraries.
+The symptom of this is a segmentation fault soon after starting Quake.
+
+If you want to use a newer version of Mesa (like 3.x) with Quake on
+RedHat 5.x then read on.
+
+The solution to the C library problem is to force Mesa to use libc5.
+libc5 is in /usr/i486-linux-libc5/lib on RedHat 5.x systems.
+
+Emil Briggs (briggs@tick.physics.ncsu.edu) nicely gave me the following
+info:
+
+> I only know what works on a RedHat 5.0 distribution. RH5 includes
+> a full set of libraries for both libc5 and glibc. The loader ld.so
+> uses the libc5 libraries in /usr/i486-linux-libc5/lib for programs
+> linked against libc5 while it uses the glibc libraries in /lib and
+> /usr/lib for programs linked against glibc.
+>
+> Anyway I changed line 41 of mklib.glide to
+> GLIDELIBS="-L/usr/local/glide/lib -lglide2x -L/usr/i486-linux-libc5/lib"
+>
+> And I started quake2 up with a script like this
+> #!/bin/csh
+> setenv LD_LIBRARY_PATH /usr/i486-linux-libc5/lib
+> setenv MESA_GLX_FX f
+> ./quake2 +set vid_ref gl
+> kbd_mode -a
+> reset
+
+
+I've already patched the mklib.glide file. You'll have to start Quake
+with the script shown above though.

+Daryll Strauss writes:
+
+Here's my thoughts on the problem. On a RH 5.x system, you can NOT build
+a libc5 executable or library. Red Hat just doesn't include the right
+stuff to do it.
+
+Since Quake is a libc5 based application, you are in trouble. You need
+libc5 libraries.
+
+What can you do about it? Well there's a package called gcc5 that does
+MOST of the right stuff to compile with libc5. (It brings back older
+header files, makes appropriate symbolic links for libraries, and sets
+up the compiler to use the correct directories) You can find gcc5 here:
+ftp://ecg.mit.edu/pub/linux/gcc5-1.0-1.i386.rpm
+
+No, this isn't quite enough. There are still a few tricks to getting
+Mesa to compile as a libc5 application. First you have to make sure that
+every compile uses gcc5 instead of gcc. Second, in some cases the link
+line actually lists -L/usr/lib which breaks gcc5 (because it forces you
+to use the glibc version of things)
+
+If you get all the stuff correctly compiled with gcc5 it should work.
+I've run Mesa 3.0B6 and its demos in a window with my Rush on a Red Hat
+5.1 system. It is a big hassle, but it can be done. I've only made Quake
+segfault, but I think that's from my libRush using the wrong libc.
+
+Yes, mixing libc5 and glibc is a major pain. I've been working to get
+all my libraries compiling correctly with this setup. Someone should
+make an RPM out of it and feed changes back to Brian once they get it
+all working. If no one else has done so by the time I get the rest of my
+stuff straightened out, I'll try to do it myself.

+Mesa Threads README
+-------------------
+
+Thread safety was introduced in Mesa 2.6 by John Stone and
+Christoph Poliwoda.
+
+It was redesigned in Mesa 3.3 so that thread safety is
+supported by default (on systems which support threads,
+that is). There is no measurable penalty on single
+threaded applications.
+
+NOTE that the only _driver_ which is thread safe at this time
+is the OS/Mesa driver!
+
+
+At present the mthreads code supports three thread APIS:
+ 1) POSIX threads (aka pthreads).
+ 2) Solaris / Unix International threads.
+ 3) Win32 threads (Win 95/NT).
+
+Support for other thread libraries can be added src/glthread.[ch]
+
+
+In order to guarantee proper operation, it is
+necessary for both Mesa and application code to use the same threads API.
+So, if your application uses Sun's thread API, then you should build Mesa
+using one of the targets for Sun threads.
+
+The mtdemos directory contains some example programs which use
+multiple threads to render to osmesa rendering context(s).
+
+Linux users should be aware that there exist many different POSIX
+threads packages. The best solution is the linuxthreads package
+(http://pauillac.inria.fr/~xleroy/linuxthreads/) as this package is the
+only one that really supports multiprocessor machines (AFAIK). See
+http://pauillac.inria.fr/~xleroy/linuxthreads/README for further
+information about the usage of linuxthreads.
+
+If you are interested in helping with thread safety work in Mesa
+join the Mesa developers mailing list and post your proposal.
+
+
+Regards,

+VMS support contributed by Jouk Jansen (joukj@hrem.stm.tudelft.nl)
+
+
+The latest version was tested on a VMSAlpha7.2 system using DECC6.0, but
+probably also works for other versions.
+
+At the moment only the libraries LIBMESGL.EXE/LIBMESGL.OLB,
+LIBMESAGLU.EXE/LIBMESAGLU.OLB and LIBGLUT.EXE/LIBGLUT.OLB and the demos of the
+directory [.DEMOS] can be build.
+However, feel free to create the missing "decrip.mms-files" in the other
+directories.
+
+ The make files were tested
+using the DIGITAL make utility called MMS. There is also a public domain
+clone available (MMK) and I think, but it is not tested, that this
+utility will give (hardly) any problem.
+
+To make everything just type MMS (or MMK) in the main directory of
+mesagl. For MMS the deafult makefile is called descrip.mms, and
+that is what I have called it. I included alse some config files,
+all having mms somewhere in the name which all the makefiles need
+(just as your unix makefiles).
+
+On Alpha platforms at default a sharable images for the libraries are created.
+To get a static library make it by typing MMS/MACRO=(NOSHARE=1).
+On VAX platforms only static libraries can be build.
+
+23-sep-2005
+changed default compilation to use /float=ieee/ieee=denorm. The reason for
+this is that it makes Mesa on OpenVMS better compatible with other platforms
+and other packages for VMS that I maintain.
+For more information see
+ http://nchrem.tnw.tudelft.nl/openvms
+ https://bugs.freedesktop.org/show_bug.cgi?id=4270
+You may want to compile Mesa to use VAX-floating point arithmetic, instead
+of IEEE floating point by removing the /float=IEEE/denorm flag from the
+compiler options in the descrip.mms files.

+
+Quick Start
+----- -----
+
+Unzip the MesaLib, MesaGLUT, and MesaDemos ZIP files into the same
+directory. The libs and demos build separately, so if you do not care
+about the demos or GLUT, you only need to unzip MesaLib. If you unzip
+more than one ZIP file, they all need to be unzipped into the same
+directory. Don't worry, you will not overwrite anything.
+
+The Windows build system uses Microsoft Visual Studio. Project files
+for a specific version of Visual Studio are in their own directory in
+the top-level "windows" directory. For example, Visual Studio 8 files
+are in windows/VC8.
+
+Support has been dropped for versions of Visual Studio prior to 8. The
+main reason is because Microsoft now provides a free compiler and
+developer environment. Visual Studio Express can be found at
+
+http://msdn.microsoft.com/vstudio/express/visualc/default.aspx
+
+You'll also need the Platform SDK. Instructions for obtaining and
+using the SDK with Visual Studio Express can be found at
+
+http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/
+
+The project files to build the core Mesa library, Windows Mesa
+drivers, OSMesa, and GLU are in the mesa directory. The project files
+to build GLUT and some demo programs are in the progs directory.
+
+Makefiles are no longer shipped or supported, but can be generated
+from the projects using Visual Studio.
+
+
+Windows Drivers
+------- -------
+
+At this time, only the GDI driver is known to work. Most of the demos
+in progs/demos should work with this driver.
+
+Source code also exists in the tree for other drivers in
+src/mesa/drivers/windows, but the status of this code is unknown.
+
+The GDI driver operates basically by writing pixel spans into a DIB
+section and then blitting the DIB to the window. The driver was
+recently cleaned up and rewitten and so may have bugs or may be
+missing some functionality. The older versions of the CVS source may
+be useful in figuring out any problems, or report them to me.
+
+To build Mesa with the GDI driver, build the mesa, gdi, and glu
+projects in the Visual Studio workspace found at
+
+ windows/VC8/mesa/mesa.sln
+
+The osmesa DLL can also be built with the osmesa project.
+
+The build system creates a lib top-level directory and copies
+resulting LIB and DLL files to this lib directory. The files are:
+
+ OPENGL32.LIB, GLU32.LIB, OSMESA32.LIB
+ OPENGL32.DLL, GLU32.DLL, OSMESA32.DLL
+
+If the MesaDemos ZIP file was extracted, the DLL files are also copied
+to the demos directory. This facilitates running the demos as described
+below.
+
+
+GLUT and Demos
+---- --- -----
+
+A Visual Studio workspace can be found at
+
+ windows/VC8/progs/progs.sln
+
+It can be used to build GLUT and a few demos. The GLUT lib and DLL
+are copied to the top-level lib directory, along with the Mesa libs.
+
+The demo build system expects to find the LIB files in the top level
+lib directory, so you must build the Mesa libs first. The demo
+executables are placed in the demos directory, because some of them
+rely on data files found there. Also, the Mesa lib DLL's were copied
+there by the Mesa lib build process. Therefore, you should be able to
+simply run the demo executables from the demo directory.
+
+If you want to run the demos from the Visual Studio, you may have to
+change the startup directory and explicitly state where the executables are.
+
+You may also build all the demo programs by using a makefile. Go to
+the progs/demos directory and make sure you have executed VCVARS32.BAT
+or whatever setup script is appropriate for your compiler. Then,
+
+ nmake -f Makefile.win
+
+should build all the demos.

+
+VC8
+---
+
+No notes.
+
+
+General
+-------
+
+After building, you can copy the above DLL files to a place in your
+PATH such as $SystemRoot/SYSTEM32. If you don't like putting things
+in a system directory, place them in the same directory as the
+executable(s). Be careful about accidentially overwriting files of
+the same name in the SYSTEM32 directory.
+
+The DLL files are built so that the external entry points use the
+stdcall calling convention.
+
+Static LIB files are not built. The LIB files that are built with are
+the linker import files associated with the DLL files.
+
+The si-glu sources are used to build the GLU libs. This was done
+mainly to get the better tessellator code.
+
+To build "mangled" Mesa, add the preprocessor define USE_MGL_NAMESPACE
+to the project settings. You will also need to edit src/mesa.def to
+change all the gl* symbols to mgl*. Because this is easy to do with a
+global replace operation in a text editor, no additional mangled
+version of mesa.def is maintained or shipped.
+
+If you have a Windows-related build problem or question, it is
+probably better to direct it to me (kschultz@users.sourceforge.net),
+rather than directly to the other Mesa developers. I will help you as
+much as I can. I also monitor the Mesa mailing lists and will answer
+questions in this area there as well.

+
+ WindML Driver for Mesa 4.0
+
+
+Requirements
+------------
+
+Tornado 2 + WindML, Cumulative Patchs are recommended.
+
+I suppose you have a valid WindML installation. Double buffer hardware
+gives better performance than double buffer software so if you can
+compile your WindML driver with this option, just do it. I/O
+redirection is adviced in target server.
+
+
+Tested on
+---------
+
+During the development, my main target was a CoolMonster:
+- Video card: CT69000
+- CPU: PENTIUM 266MHz
+
+and my host a Windows NT + Tornado 2.
+
+
+Installation
+------------
+
+1. Mesa sources must be in root directory (C:\)
+
+2. Add the following line to your torVars.bat:
+set MESA_BASE=C:\Mesa
+
+OR copy the new torVars.bat in your bin path:
+c:/Mesa/src/ugl/tornado/torVars.sample ->
+/mnt/nt/Tornado/host/x86-win32/bin/torVars (for example)
+
+3. In a command prompt:
+$ torVars
+$ cd c:\Mesa
+$ make -f Makefile.ugl CPU=PENTIUM
+
+Take a long while...
+
+5. Include all the files from ugldemos folder to build some downloadable
+ application modules
+
+4. Download UGL/Mesa object files on target
+
+For example via the WindShell:
+ld < c:\Tornado\target\lib\objMesaGL.o
+ld < c:\Tornado\target\lib\objMesaUGL.o
+ld < c:\Tornado\target\lib\objMesaGLU.o
+ld < c:\Tornado\target\lib\objGLUTshapes.o
+ld < c:\Tornado\target\lib\objMesaOS.o
+
+You can put the previous lines in a file and use:
+< filename
+
+6. Download the application modules.
+
+7. In WindShell, run:
+-> uglalldemos
+
+During the show some messages will appear, it provides some useful
+information on key management.
+
+
+Coding
+------
+
+Sample Usage:
+
+In addition to the usual ugl calls to initialize UGL, (may be find an
+input driver), you must do the following to use the UGL/Mesa interface:
+
+1. Call uglMesaCreateContext() to create a UGL/Mesa rendering context,
+ given the display format.
+
+2. Call uglMesaMakeCurrent() to bind the UGL/Mesa buffers to an
+ UGL/Mesa Context and to make the context the current one.
+
+3. Make gl* calls to render your graphics.
+
+4. Use uglMesaSwapBuffers() when double buffering to swap front/back buffers.
+
+5. Before the UGL is destroyed, call MesaDestroyContext().
+
+6. Before exiting, call if required uglEventQDestroy and then
+ uglDeinitialize();
+
+Limitations
+-----------
+
+I found the following limitations in my driver :
+ - Color Indexed management is only in 8 bits
+ - It's possible to mix UGL/OpenGL application with a software
+ double buffer

+
+ Mesa 3.1 release notes
+
+ PLEASE READ!!!!
+
+
+New copyright
+-------------
+
+Mesa 3.1 will be distributed under an XFree86-style copyright instead
+of the GNU LGPL.
+
+
+New directories
+---------------
+
+All documentation files are now in the docs/ directory.
+All shell scripts are now in the bin/ directory.
+
+
+New library names
+-----------------
+
+Formerly, the main Mesa library was named libMesaGL.so (or libMesaGL.a)
+and the GLU library was named libMesaGLU.so (or libMesaGLU.a).
+
+Now, the main library is named libGL.so (or libGL.a) and the GLU library
+is named libGLU.so (or libGLU.a).
+
+The change allows Mesa to be more easily substituted for OpenGL.
+Specifically, the linker/loader on some Unix-like systems won't
+allow libMesaGL.so to be used instead of libGL.so if the application
+was linked with the former.
+
+Warning: if you have another OpenGL implementation installed on your
+system (i.e. you have another OpenGL libGL.so) you'll have to be
+carefull about which library (OpenGL or Mesa) you link against. Be
+aware of -L linker flags and the value of the LD_LIBRARY_PATH environment
+variable.
+
+
+New library versioning
+----------------------
+
+Previously, the Mesa GL library was named libMesaGL.so.3.0
+To better support Linux/OpenGL standards, the Mesa GL library is now
+named libGL.so.1.2.030100 This indicates version 1.2 of the OpenGL spec
+and Mesa implementation 3.1.0
+
+In the long term this will allow better interoperability with other
+OpenGL implementations, especially on Linux. In the short term,
+OpenGL apps may have to be relinked to use the new library naming.
+
+
+
+New makefiles
+-------------
+
+The old Makefiles found in the various directories have been renamed
+to Makefile.X11 in order to prevent filename collisions with autoconfig-
+generated Makefiles.
+
+The top-level Makefile simply includes Makefile.X11
+If your top-level Makefile get's overwritten/destroyed you can restore
+it by copying Makefile.X11 to Makefile
+
+
+New extensions
+--------------
+
+GL_EXT_stencil_wrap
+ Implements two new stencil operations: GL_INCR_WRAP_EXT and
+ GL_DECR_WRAP_EXT which allow stencil increment and decrement
+ without clamping.
+
+GL_INGR_blend_func_separate
+ Allows specification of blend factors for RGB and Alpha independently.
+ (INGR = Intergraph)
+
+GL_ARB_multitexture
+ Multiple simultaneous textures. (ARB = Architecture Review Board)
+
+GL_NV_texgen_reflection
+ nVidia texgen extension for better reflection mapping.
+
+GL_PGI_misc_hints
+ Assorted transformation hints.
+
+GL_EXT_compiled_vertex_array
+ Compiled vertex arrays.
+
+GL_EXT_clip_volume_hint
+ Allows one to disable clip volume (frustum) testing.
+
+
+
+Extensions removed
+------------------
+
+GL_EXT_multitexture - obsolete in favor of GL_ARB_multitexture
+
+
+
+Config file
+-----------
+
+By default, /etc/mesa.conf will be read when Mesa starts. This
+file controls default hints, enable/disable of extensions, and
+more. See the CONFIG file for documentation.
+
+
+
+Optimizations
+-------------
+
+Keith Whitwell has contributed significant optimizations to Mesa's
+vertex transformation code. Basically, the whole transformation
+stage of Mesa has been rewritten.
+
+It's impossible to give a speedup factor. You'll just have to
+try your app and see how it performs.
+
+
+
+Device Driver changes
+---------------------
+
+A bunch of new device driver functions have been added. See src/dd.h
+Keith Harrison contributed many of them. I've been planning on adding
+a bunch of functions like these to make writing hardware drivers easier.
+More such function will probably be added in the near future.
+
+
+
+Miscellaneous
+-------------
+
+util/glstate.c has some handy functions for debugging. Basically, it
+offers a simple function for printing GL state variables. It's not
+finished yet. There's a LOT more GLenum records to be added (see the
+code). Anyone want to help?
+

+
+ Mesa 3.3 release notes
+
+ July 21, 2000
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.3) designate new developmental releases.
+Even numbered versions (such as 3.2.1) designate stable releases.
+
+Mesa 3.3 has a undergone many internal changes since version 3.2
+and features a lot of new extensions. 3.3 is expected to be pretty
+stable, but perhaps not as stable as 3.2 which has been used by
+thousands of users over the past months.
+
+Everyone is encouraged to try Mesa 3.3. Bugs should be reported to
+the Mesa bug database on www.sourceforge.net.
+
+
+
+Header file / GLenum changes
+----------------------------
+
+The gl.h and glu.h headers now use #defines to define all GL_* tokens
+instead of C-language enums. This change improves Mesa/OpenGL
+interoperability.
+
+
+
+New API dispatch code
+---------------------
+
+The core Mesa gl* functions are now implemented with a new dispatch
+(jump table) which will allow simultaneous direct/indirect rendering.
+
+The code is found in the glapi*.[ch] files.
+
+Of interest: the actual "glFooBar" functions are generated with
+templatized code defined in glapitemp.h and included by glapi.c
+The glapitemp.h template should be reusable for all sorts of OpenGL
+projects.
+
+The new dispatch code has also optimized with x86 assembly code.
+This optimization eliminates copying the function arguments during
+dispatch.
+
+
+
+New thread support
+------------------
+
+Thread support in Mesa has been rewritten. The glthread.[ch] files
+replace mthreads.[ch]. Thread safety is always enabled (on platforms
+which support threads, that is). There is virtually no performance
+penalty for typical single-thread applications. See the glapi.c
+file for details.
+
+The Xlib driver (XMesa) is now thread-safe as well. Be sure to
+call XInitThreads() in your app first. See the xdemos/glthreads.c
+demo for an example.
+
+
+
+Make configuration changes
+--------------------------
+
+If you use the old-style (non GNU automake) method to build Mesa note
+that several of the configuration names have changed:
+
+ Old name New name
+ ------------- ----------------
+ linux-elf linux
+ linux linux-static
+ linux-386-elf linux-386
+ linux-386 linux-386-static
+ etc.
+
+
+
+New extensions
+--------------
+
+GL_ARB_transpose_matrix
+ Adds glLoadTransposeMatrixARB() and glMultTransposeMatrixARB()
+ functions.
+
+GL_ARB_texture_cube_map
+ For cube-based reflection mapping.
+
+GL_EXT_texture_add_env
+ Adds GL_ADD texture environment mode.
+ See http://www.berkelium.com/OpenGL/EXT/texture_env_add.txt
+
+GL_EXT_texture_lod_bias
+ Allows mipmapped texture blurring and sharpening.
+
+GLX_EXT_visual_rating extension
+ This extension has no effect in stand-alone Mesa (used for DRI).
+
+GL_HP_occlusion_test
+ Used for bounding box occlusion testing (see demos/occlude.c).
+
+GL_SGIX_pixel_texture / GL_SGIS_pixel_texture
+ Lets glDraw/CopyPixels draw a texture coordinate image.
+
+GL_SGI_color_matrix
+ Adds a color matrix and another set of scale and bias parameters
+ to the glDraw/CopyPixels paths.
+
+GL_SGI_color_table
+ Adds additional color tables to the glDraw/Read/CopyPixels paths.
+
+GL_EXT_histogram
+ Compute histograms for glDraw/Read/CopyPixels.
+
+GL_EXT_blend_func_separate
+ This is the same as GL_INGR_blend_func_separate.
+
+GL_ARB_texture_cube_mapping
+ 6-face cube mapping, nicer than sphere mapping
+
+GL_EXT_texture_env_combine
+ For advanced texture environment effects.
+
+
+Documentation for all these functions can be found at
+http://oss.sgi.com/projects/ogl-sample/registry/
+
+
+
+GLX_SGI_make_current_read functionality
+---------------------------------------
+
+The functionality of this extension is needed for GLX 1.3 (and required
+for the Linux/OpenGL standards base).
+
+Implementing this function required a **DEVICE DRIVER CHANGE**.
+The old SetBuffer() function has been replaced by SetReadBuffer() and
+SetDrawBuffer(). All device drivers will have to be updated because
+of this change.
+
+The new function, glXMakeContextCurrent(), in GLX 1.3 now works in Mesa.
+The xdemos/wincopy.c program demonstrates it.
+
+
+
+Image-related code changes
+--------------------------
+
+The imaging path code used by glDrawPixels, glTexImage[123]D,
+glTexSubImage[123], etc has been rewritten. It's now faster,
+uses less memory and has several bug fixes. This work was
+actually started in Mesa 3.1 with the glTexImage paths but has now
+been carried over to glDrawPixels as well.
+
+
+
+Device driver interface changes
+-------------------------------
+
+Added new functions for hardware stencil buffer support:
+ WriteStencilSpan
+ ReadStencilSpan
+ WriteStencilPixels
+ ReadStencilPixels
+
+
+Removed old depth buffer functions:
+ AllocDepthBuffer
+ DepthTestSpan
+ DepthTestPixels
+ ReadDepthSpanFloat
+ ReadDepthSpanInt
+
+
+Added new depth buffer functions:
+ WriteDepthSpan
+ ReadDepthSpan
+ WriteDepthPixels
+ ReadDepthPixels
+
+ These functions always read/write 32-bit GLuints. This will allow
+ drivers to have anywhere from 0 to 32-bit Z buffers without
+ recompiling for 16 vs 32 bits as was previously needed.
+
+
+New texture image functions
+ The entire interface for texture image specification has been updated.
+ With the new functions, it's optional for Mesa to keep an internal copy
+ of all textures. Texture download should be a lot faster when the extra
+ copy isn't made.
+
+Misc changes
+ TexEnv now takes a target argument
+ Removed UseGlobalTexturePalette (use Enable function instead)
+
+
+Also added
+ ReadPixels
+ CopyPixels
+
+
+The SetBufffer function has been replaced by SetDrawBuffer and
+SetReadBuffer functions. This lets core Mesa independently
+specify which buffer is to be used for reading and which for
+drawing.
+
+The Clear function's mask parameter has changed. Instead of
+mask being the flags specified by the user to glClear, the
+mask is now a bitmask of the DD_*_BIT flags in dd.h. Now
+multiple color buffers can be specified for clearing (ala
+glDrawBuffers). The driver's Clear function must also
+check the glColorMask glIndexMask, and glStencilMask settings
+and do the right thing. See the X/Mesa, OS/Mesa, or FX/Mesa
+drivers for examples.
+
+
+The depth buffer changes shouldn't be hard to make for existing
+drivers. In fact, it should simply the code. Be careful with
+the depthBits value passed to gl_create_context(). 1 is a bad
+value! It should normally be 0, 16, 24, or 32.
+
+
+gl_create_framebuffer() takes new arguments which explicitly tell
+core Mesa which ancillary buffers (depth, stencil, accum, alpha)
+should be implemented in software. Mesa hardware drivers should
+carefully set these flags depending on which buffers are in the
+graphics card.
+
+
+
+Internal constants
+------------------
+
+Point and line size range and granularity limits are now stored
+in the gl_constants struct, which is the Const member of GLcontext.
+The limits are initialized from values in config.h but may be
+overridden by device drivers to reflect the limits of that driver's
+hardware.
+
+Also added constants for NumAuxBuffers and SubPixelBits.
+
+
+
+OpenGL Conformance
+------------------
+
+Mesa now passes all the OpenGL 1.1 conformance tests, except for
+antialiased lines. AA lines fail on some, but not all, the tests.
+In order to fix the remaining failures, a new AA line algorithm will
+be needed (which computes coverage values for end-point fragments).
+This will be done for Mesa 3.5/3.6.
+
+
+
+OpenGL 1.2 GL_ARB_imaging subset
+--------------------------------
+
+Mesa 3.3 implements all the features of GL_ARB_imaging except for
+image convolution. This will (hopefully) be done for Mesa 3.5/3.6.
+
+

+ Mesa 3.5 release notes
+
+ June 21, 2001
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.5) designate new developmental releases.
+Even numbered versions (such as 3.4) designate stable releases.
+
+The biggest change in Mesa 3.5 is a complete overhaul of the source
+code in order to make it more modular. This was driven by the DRI
+hardware drivers. It simplifies the DRI drivers and opens the door
+to hardware transform/clip/lighting (TCL). Keith Whitwell can take
+the credit for that.
+
+
+
+Driver Support
+--------------
+
+The device driver interface in Mesa 3.5 has changed a lot since Mesa 3.4
+Not all of the older Mesa drivers have been updated. Here's the status:
+
+Driver Status
+---------------------- -----------
+XMesa (Xlib) updated
+OSMesa (off-screen) updated
+FX (3dfx Voodoo1/2) updated
+SVGA updated
+GGI not updated
+Windows/Win32 not updated
+DOS/DJGPP not updated
+BeOS not updated
+Allegro not updated
+D3D not updated
+DOS not updated
+
+We're looking for volunteers to update the remaining drivers. Please
+post to the Mesa3d-dev mailing list if you can help.
+
+
+
+GLU 1.3
+-------
+
+Mesa 3.5 includes the SGI Sample Implementation (SI) GLU library.
+This version of GLU supports the GLU 1.3 specification. The old
+Mesa GLU library implemented the 1.1 specification. The SI GLU
+library should work much better.
+
+You'll need a C++ compiler to compile the SI GLU library. This may
+be a problem on some systems.
+
+
+
+New Extensions
+--------------
+
+GL_EXT_convolution
+ Adds image convolution to glRead/Copy/DrawPixels/TexImage.
+
+GL_ARB_imaging
+ This is the optional imaging subset of OpenGL 1.2.
+ It's the GL_EXT_convolution, GL_HP_convolution_border_modes,
+ GL_EXT_histogram, GL_EXT_color_table, GL_EXT_color_subtable
+ GL_EXT_blend_color, GL_EXT_blend_minmax, GL_EXT_blend_subtract
+ and GL_SGI_color_matrix extensions all rolled together.
+ This is supported in all software renderers but not in all
+ hardware drivers (3dfx for example).
+
+GL_ARB_texture_compression
+ This is supported in Mesa but only used by the 3dfx DRI drivers
+ for Voodoo4 and later.
+
+GL_ARB_texture_env_add
+ This is identical to GL_EXT_texture_env_add.
+
+GL_NV_blend_square
+ Adds extra blend source and dest factors which allow squaring
+ of color values.
+
+GL_EXT_fog_coord
+ Allows specification of a per-vertex fog coordinate instead of
+ having fog always computed from the eye distance.
+
+GL_EXT_secondary_color
+ Allows specifying the secondary (specular) color for each vertex
+ instead of getting it only from lighting in GL_SEPARATE_SPECULAR_COLOR
+ mode.
+
+GL_ARB_texture_env_combine
+ Basically the same as GL_EXT_texture_env_combine
+
+GL_ARB_texture_env_add extension
+ Texture addition mode.
+
+GL_ARB_texture_env_dot3 extension
+ Dot product texture environment.
+
+GL_ARB_texture_border_clamp
+ Adds GL_CLAMP_TO_BORDER_ARB texture wrap mode
+
+GL_SGIX_depth_texture, GL_SGIX_shadow and GL_SGIX_shadow_ambient
+ Implements a shadow casting algorithm based on depth map textures
+
+GL_SGIS_generate_mipmap
+ Automatically generate lower mipmap images whenever the base mipmap
+ image is changed with glTexImage, glCopyTexImage, etc.
+
+
+
+libOSMesa.so
+------------
+
+libOSMesa.so is a new library which contains the OSMesa interface for
+off-screen rendering. Apps which need the OSMesa interface should link
+with both -lOSMesa and -lGL. This change was made so that stand-alone
+Mesa works the same way as XFree86/DRI's libGL.
+
+
+
+Device Driver Changes / Core Mesa Changes
+-----------------------------------------
+
+The ctx->Driver.LogicOp() function has been removed. It used to
+be called during state update in order to determine if the driver
+could do glLogicOp() operations, and if not, set the SWLogicOpEnabled
+flag. Drivers should instead examine the LogicOp state themselves
+and choose specialized point, line, and triangle functions appropriately,
+or fall back to software rendering. The Xlib driver was the only driver
+to use this function. And since the Xlib driver no longer draws
+points, lines or triangles using Xlib, the LogicOp function isn't needed.
+
+The ctx->Driver.Dither() function has been removed. Drivers should
+detect dither enable/disable via ctx->Driver.Enable() instead.
+
+The ctx->Driver.IndexMask() and ctx->Driver.ColorMask() functions
+are now just called from glIndexMask and glColorMask like the other
+GL state-changing functions. They are no longer called from inside
+gl_update_state(). Also, they now return void. The change was made
+mostly for sake of uniformity.
+
+The NEW_DRVSTATE[0123] flags have been removed. They weren't being used
+and are obsolete w.r.t. the way state updates are done in DRI drivers.
+
+
+Removed obsolete gl_create_visual() and gl_destroy_visual().
+
+Renamed functions (new namespace):
+
+old new
+gl_create_framebuffer _mesa_create_framebuffer
+gl_destroy_framebuffer _mesa_destroy_framebuffer
+gl_create_context _mesa_create_context
+gl_destroy_context _mesa_destroy_context
+gl_context_initialize _mesa_context_initialize
+gl_copy_context _mesa_copy_context
+gl_make_current _mesa_make_current
+gl_make_current2 _mesa_make_current2
+gl_get_current_context _mesa_get_current_context
+gl_flush_vb _mesa_flush_vb
+gl_warning _mesa_warning
+gl_compile_error _mesa_compile_error
+
+
+All the drivers have been updated, but not all of them have been
+tested since I can't test some platforms (DOS, Windows, Allegro, etc).
+
+
+X/Mesa Driver
+-------------
+
+The source files for the X/Mesa driver in src/X have been renamed.
+The xmesa[1234].c files are gone. The new files are xm_api.c,
+xm_dd.c, xm_line.c, xm_span.c and xm_tri.c.
+
+
+
+Multitexture
+------------
+
+Eight texture units are now supported by default.
+
+
+
+OpenGL SI related changes
+-------------------------
+
+In an effort to make Mesa's internal interfaces more like the OpenGL
+SI interfaces, a number of changes have been made:
+
+1. Importing the SI's glcore.h file which defines a number of
+interface structures like __GLimports and __GLexports.
+
+2. Renamed "struct gl_context" to "struct __GLcontextRec".
+
+3. Added __glCoreCreateContext() and __glCoreNopDispatch() functions.
+
+4. The GLcontext member Visual is no longer a pointer.
+
+5. New file: imports.c to setup default import functions for Mesa.
+
+
+
+
+16-bit color channels
+---------------------
+
+There's experimental support for 16-bit color channels (64-bit pixels)
+in Mesa 3.5. Only the OSMesa interface can be used for 16-bit rendering.
+Type "make linux-osmesa16" in the top-level directory to build the
+special libOSMesa16.so library.
+
+This hasn't been tested very thoroughly yet so please file bug reports
+if you have trouble.
+
+In the future I hope to implement support for 32-bit, floating point
+color channels.

+ Mesa 4.0 release notes
+
+ October 18, 2001
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.3) designate new developmental releases.
+Even numbered versions (such as 3.4) designate stable releases.
+
+Mesa version 4.0 signifies two things:
+
+ 1. A stabilization of the 3.5 development release
+ 2. Implementation of the OpenGL 1.3 specification
+
+
+Note that the Mesa major version number is incremented with the OpenGL
+minor version number:
+
+ Mesa 1.x == OpenGL 1.0
+ Mesa 2.x == OpenGL 1.1
+ Mesa 3.x == OpenGL 1.2
+ Mesa 4.x == OpenGL 1.3
+
+
+
+New Features
+------------
+
+Mesa 3.5 already had all the new features of OpenGL 1.3, implemented as
+extensions. These extensions were simply promoted to standard features:
+
+ GL_ARB_multisample
+ GL_ARB_multitexture
+ GL_ARB_texture_border_clamp
+ GL_ARB_texture_compression
+ GL_ARB_texture_cube_map
+ GL_ARB_texture_env_add
+ GL_ARB_texture_env_combine
+ GL_ARB_texture_env_dot3
+ GL_ARB_transpose_matrix
+
+In Mesa 4.0 the functions defined by these extensions are now available
+without the "ARB" suffix. For example, glLoadTransposeMatrixf() is now
+a standard API function. The new functions in OpenGL 1.3 and Mesa 4.0 are:
+
+ glActiveTexture
+ glClientActiveTexture
+ glCompressedTexImage1D
+ glCompressedTexImage2D
+ glCompressedTexImage3D
+ glCompressedTexSubImage1D
+ glCompressedTexSubImage2D
+ glCompressedTexSubImage3D
+ glGetCompressedTexImage
+ glLoadTransposeMatrixd
+ glLoadTransposeMatrixf
+ glMultiTexCoord1d
+ glMultiTexCoord1dv
+ glMultiTexCoord1f
+ glMultiTexCoord1fv
+ glMultiTexCoord1i
+ glMultiTexCoord1iv
+ glMultiTexCoord1s
+ glMultiTexCoord1sv
+ glMultiTexCoord2d
+ glMultiTexCoord2dv
+ glMultiTexCoord2f
+ glMultiTexCoord2fv
+ glMultiTexCoord2i
+ glMultiTexCoord2iv
+ glMultiTexCoord2s
+ glMultiTexCoord2sv
+ glMultiTexCoord3d
+ glMultiTexCoord3dv
+ glMultiTexCoord3f
+ glMultiTexCoord3fv
+ glMultiTexCoord3i
+ glMultiTexCoord3iv
+ glMultiTexCoord3s
+ glMultiTexCoord3sv
+ glMultiTexCoord4d
+ glMultiTexCoord4dv
+ glMultiTexCoord4f
+ glMultiTexCoord4fv
+ glMultiTexCoord4i
+ glMultiTexCoord4iv
+ glMultiTexCoord4s
+ glMultiTexCoord4sv
+ glMultTransposeMatrixd
+ glMultTransposeMatrixf
+ glSampleCoverage
+ glSamplePass
+
+
+GLX 1.4 is the companion to OpenGL 1.3. The only new features in GLX 1.4
+are support for multisampling and the GLX_ARB_get_proc_address extension.
+glXGetProcAddress() is the only new function in GLX 1.4.
+
+
+
+Multisample and Texture Compression
+-----------------------------------
+
+The OpenGL 1.3 specification allows the multisample and texture compression
+features to essentially be no-ops. For example, if you query for multisample
+support you'll find none, but the API functions work.
+
+Similarly, texture compression is not implemented by any of the software
+drivers but you can specify a generic compressed texture format (like
+GL_COMPRESSED_RGBA) to glTexImage2D and it'll be accepted.
+
+
+
+Device Drivers
+--------------
+
+Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the
+device driver. If the driver enables all the ARB extensions which are part
+of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3". Otherwise,
+it'll return "1.2".
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time. We rely on volunteers to maintain many of the drivers.
+Here's the current status of all included drivers:
+

+
+New Features in Mesa 4.1
+------------------------
+
+New extensions. Docs at http://oss.sgi.com/projects/ogl-sample/registry/
+
+GL_NV_vertex_program
+
+ NVIDIA's vertex programming extension
+
+GL_NV_vertex_program1_1
+
+ A few features built on top of GL_NV_vertex_program
+
+GL_ARB_window_pos
+
+ This is the ARB-approved version of GL_MESA_window_pos
+
+GL_ARB_depth_texture
+
+ This is the ARB-approved version of GL_SGIX_depth_texture.
+ It allows depth (Z buffer) data to be stored in textures.
+ This is used by GL_ARB_shadow
+
+GL_ARB_shadow
+
+ Shadow mapping with depth textures.
+ This is the ARB-approved version of GL_SGIX_shadow.
+
+GL_ARB_shadow_ambient
+
+ Allows one to specify the luminance of shadowed pixels.
+ This is the ARB-approved version of GL_SGIX_shadow_ambient.
+
+GL_EXT_shadow_funcs
+
+ Extends the set of GL_ARB_shadow texture comparision functions to
+ include all eight of standard OpenGL dept-test functions.
+
+GL_ARB_point_parameters
+
+ This is basically the same as GL_EXT_point_parameters.
+
+GL_ARB_texture_env_crossbar
+
+ Allows any texture combine stage to reference any texture source unit.
+
+GL_NV_point_sprite
+
+ For rendering points as textured quads. Useful for particle effects.
+
+GL_NV_texture_rectangle (new in 4.0.4 actually)
+
+ Allows one to use textures with sizes that are not powers of two.
+ Note that mipmapping and several texture wrap modes are not allowed.
+
+GL_EXT_multi_draw_arrays
+
+ Allows arrays of vertex arrays to be rendered with one call.
+
+GL_EXT_stencil_two_side
+
+ Separate stencil modes for front and back-facing polygons.
+
+GLX_SGIX_fbconfig & GLX_SGIX_pbuffer
+
+ Off-screen rendering support.
+
+GL_ATI_texture_mirror_once
+
+ Adds two new texture wrap modes: GL_MIRROR_CLAMP_ATI and
+ GL_MIRROR_CLAMP_TO_EDGE_ATI.
+
+
+
+Device Driver Status
+--------------------
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time. We rely on volunteers to maintain many of these drivers.
+Here's the current status of all included drivers:
+
+
+Driver Status
+---------------------- ---------------------
+XMesa (Xlib) implements OpenGL 1.3
+OSMesa (off-screen) implements OpenGL 1.3
+FX (3dfx Voodoo1/2) implements OpenGL 1.3
+SVGA implements OpenGL 1.3
+Wind River UGL implements OpenGL 1.3
+Windows/Win32 implements OpenGL 1.3
+DOS/DJGPP implements OpenGL 1.3
+GGI implements OpenGL 1.3
+BeOS needs updating (underway)
+Allegro needs updating
+D3D needs updating
+DOS needs updating
+
+
+
+New features in GLUT
+--------------------
+
+1. Frames per second printing
+
+ GLUT now looks for an environment variable called "GLUT_FPS". If it's
+ set, GLUT will print out a frames/second statistic to stderr when
+ glutSwapBuffers() is called. By default, frames/second is computed
+ and displayed once every 5 seconds. You can specify a different
+ interval (in milliseconds) when you set the env var. For example
+ 'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval
+ to one second.
+
+ NOTE: the demo or application must call the glutInit() function for
+ this to work. Otherwise, the env var will be ignored.
+
+ Finally, this feature may not be reliable in multi-window programs.
+
+
+2. glutGetProcAddress() function
+
+ The new function:
+
+ void *glutGetProcAddress(const char *procName)
+
+ is a wrapper for glXGetProcAddressARB() and wglGetProcAddress(). It
+ lets you dynamically get the address of an OpenGL function at runtime.
+ The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the
+ GLUT version number from 3.7 since that's probably Mark Kilgard's role.
+
+ This function should probably also be able to return the address of
+ GLUT functions themselves, but it doesn't do that yet.
+
+
+
+XXX Things To Do Yet XXXX
+-------------------------
+
+isosurf with vertex program exhibits some missing triangles (probably
+when recycling the vertex buffer for long prims).
+
+
+
+Porting Info
+------------
+
+If you're porting a DRI or other driver from Mesa 4.0.x to Mesa 4.1 here
+are some things to change:
+
+1. ctx->Texture._ReallyEnabled is obsolete.
+
+ Since there are now 5 texture targets (1D, 2D, 3D, cube and rect) that
+ left room for only 6 units (6*5 < 32) in this field.
+ This field is being replaced by ctx->Texture._EnabledUnits which has one
+ bit per texture unit. If the bit k of _EnabledUnits is set, that means
+ ctx->Texture.Unit[k]._ReallyEnabled is non-zero. You'll have to look at
+ ctx->Texture.Unit[k]._ReallyEnabled to learn if the 1D, 2D, 3D, cube or
+ rect texture is enabled for unit k.
+
+ This also means that the constants TEXTURE1_*, TEXTURE2_*, etc are
+ obsolete.
+
+ The tokens TEXTURE0_* have been replaced as well (since there's no
+ significance to the "0" part:
+
+ old token new token
+ TEXTURE0_1D TEXTURE_1D_BIT
+ TEXTURE0_2D TEXTURE_2D_BIT
+ TEXTURE0_3D TEXTURE_3D_BIT
+ TEXTURE0_CUBE TEXTURE_CUBE_BIT
+ TEXTURE_RECT_BIT
+
+ These tokens are only used for the ctx->Texture.Unit[i].Enabled and
+ ctx->Texture.Unit[i]._ReallyEnabled fields. Exactly 0 or 1 bits will
+ be set in _ReallyEnabled at any time!
+
+ Q: "What's the purpose of Unit[i].Enabled vs Unit[i]._ReallyEnabled?"
+ A: The user can enable GL_TEXTURE_1D, GL_TEXTURE_2D, etc for any
+ texure unit all at once (an unusual thing to do).
+ OpenGL defines priorities that basically say GL_TEXTURE_2D has
+ higher priority than GL_TEXTURE_1D, etc. Also, just because a
+ texture target is enabled by the user doesn't mean we'll actually
+ use that texture! If a texture object is incomplete (missing mip-
+ map levels, etc) it's as if texturing is disabled for that target.
+ The _ReallyEnabled field will have a bit set ONLY if the texture
+ target is enabled and complete. This spares the driver writer from
+ examining a _lot_ of GL state to determine which texture target is
+ to be used.
+
+
+2. Tnl tokens changes
+
+ During the implementation of GL_NV_vertex_program some of the vertex
+ buffer code was changed. Specifically, the VERT_* bits defined in
+ tnl/t_context.h have been renamed to better match the conventions of
+ GL_NV_vertex_program. The old names are still present but obsolete.
+ Drivers should use the newer names.
+
+ For example: VERT_RGBA is now VERT_BIT_COLOR0 and
+ VERT_SPEC_RGB is now VERT_BIT_COLOR1.
+
+
+
+3. Read/Draw Buffer changes
+
+ The business of setting the current read/draw buffers in Mesa 4.0.x
+ was complicated. It's much simpler now in Mesa 4.1.
+
+ Here are the changes:
+
+ - Renamed ctx->Color.DrawDestMask to ctx->Color._DrawDestMask
+ - Removed ctx->Color.DriverDrawBuffer
+ - Removed ctx->Pixel.DriverReadBuffer
+ - Removed ctx->Color.MultiDrawBuffer
+ - Removed ctx->Driver.SetDrawBuffer()
+ - Removed swrast->Driver.SetReadBuffer().
+ - Added ctx->Color._DrawDestMask - a bitmask of FRONT/BACK_LEFT/RIGHT_BIT
+ values to indicate the current draw buffers.
+ - Added ctx->Pixel._ReadSrcMask to indicate the source for pixel reading.
+ The value is _one_ of the FRONT/BACK_LEFT/RIGHT_BIT values.
+ - Added ctx->Driver.DrawBuffer() and ctx->Driver.ReadBuffer().
+ These functions exactly correspond to glDrawBuffer and glReadBuffer calls.
+ Many drivers will set ctx->Driver.DrawBuffer = _swrast_DrawBuffer and
+ leave ctx->Draw.ReadBuffer NULL.
+ DRI drivers should implement their own function for ctx->Driver.DrawBuffer
+ and use it to set the current hardware drawing buffer. You'll probably
+ also want to check for GL_FRONT_AND_BACK mode and fall back to software.
+ Call _swrast_DrawBuffer() too, to update the swrast state.
+ - Added swrast->Driver.SetBuffer().
+ This function should be implemented by all device drivers that use swrast.
+ Mesa will call it to specify the buffer to use for span reading AND
+ writing and point/line/triangle rendering.
+ There should be no confusion between current read or draw buffer anymore.
+ - Added swrast->CurrentBuffer to indicate which color buffer to read/draw.
+ Will be FRONT_LEFT_BIT, BACK_LEFT_BIT, FRONT_RIGHT_BIT or BACK_RIGHT_BIT.
+ This value is usually passed to swrast->Driver.SetBuffer().
+
+
+4. _mesa_create_context() changes. This function now takes a pointer to
+ a __GLimports object. The __GLimports structure contains function
+ pointers to system functions like fprintf(), malloc(), etc.
+ The _mesa_init_default_imports() function can be used to initialize
+ a __GLimports object. Most device drivers (like the DRI drivers)
+ should use this.
+
+
+5. In tnl's struct vertex_buffer, the field "ProjectedClipCoords"
+ has been replaced by "NdcPtr" to better match the OpenGL spec's
+ terminology.
+
+
+6. Since GL_EXT_stencil_two_side has been implemented, many of the
+ ctx->Stencil fields are now 2-element arrays. For example,
+ "GLenum Ref" is now "GLenum Ref[2]" The [0] elements are the front-face
+ values and the [1] elements are the back-face values.
+ ctx->Stencil.ActiveFace is 0 or 1 to indicate the current face for
+ the glStencilOp/Func/Mask() functions.
+ ctx->Stencil.TestTwoSide controls whether or not 1 or 2-sided stenciling
+ is enabled.
+
+
+7. Removed ctx->Polygon._OffsetAny. Removed ctx->Polygon.OffsetMRD.
+
+
+8. GLfloat / GLchan changes:
+
+ - Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4].
+ ctx->Color.ClearColor is now GLfloat[4] too.
+ - Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan.
+ - ctx->Color.AlphaRef is now GLfloat.
+ - texObj->BorderColor is now GLfloat[4]. texObj->_BorderChan is GLchan[4].
+
+ This is part of an effort to remove all GLchan types from core Mesa so
+ that someday we can support 8, 16 and 32-bit color channels dynamically
+ at runtime, instead of at compile-time.
+
+
+9. GLboolean ctx->Tranform.ClipEnabled[MAX_CLIP_PLANES] has been replaced
+ by GLuint ctx->Transform.ClipPlanesEnabled. The later is a bitfield.
+
+
+10. There's a new matrix_stack type in mtypes.h used for the Modelview,
+ Projection, Color and Texcoord matrix stacks.
+
+
+11. The ctx->Current.* fields have changed a lot. Now, there's a
+ ctx->Current.Attrib[] array for all vertex attributes which matches
+ the NV vertex program conventions.

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.

+
+New Features in Mesa 5.0
+------------------------
+
+Mesa 5.0 supports OpenGL 1.4. Note Mesa's versioning convention:
+
+ OpenGL Version Mesa Version
+ ------------------------------
+ 1.0 1.x
+ 1.1 2.x
+ 1.2 3.x
+ 1.3 4.x
+ 1.4 5.x
+
+OpenGL 1.4 (and Mesa 5.0) incorporates the following OpenGL extensions as
+standard features:
+
+ GL_ARB_depth_texture
+ GL_ARB_shadow
+ GL_ARB_texture_env_crossbar
+ GL_ARB_texture_mirror_repeat
+ GL_ARB_window_pos
+ GL_EXT_blend_color

+ GL_SGIS_generate_mipmap
+
+
+
+Device Driver Status
+--------------------
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time. We rely on volunteers to maintain many of these drivers.
+Here's the current status of all included drivers:

+ Mesa 5.1 release notes
+
+ December 17, 2003
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Even-numbered versions (such as 5.0) designate stable releases.
+Odd-numbered versions (such as 5.1) designate new developmental releases.
+
+
+Bug fixes
+---------
+See the VERSIONS file for a list of bugs fixed in this release.
+
+
+
+New Features in Mesa 5.1
+------------------------
+
+GL_ARB_vertex_program / GL_ARB_fragment_program
+ Michal Krol and Karl Rasche implemented these extensions. Thanks!
+ Be aware that there may be some rough edges and lurking bugs.
+
+GL_ATI_texture_env_combine3 extension
+ This adds a few new texture combine modes.
+ Contributed by Ian Romanick.
+
+GL_SGI_texture_color_table
+ Adds a color table lookup to the RGBA texture path. There's a separate
+ color table for each texture unit.
+ Contributed by Eric Plante.
+
+GL_NV_fragment_program
+ NVIDIA's fragment-level programming feature.
+ Possible lurking bugs:
+ - the DDX and DDY commands aren't fully tested
+ - there may be bugs in the parser
+ - the TEX and TXP instructions both do perspective correction
+ - the pack/unpack instructions may not be correct
+
+GL_EXT_depth_bounds_test
+ This extension adds a scissor-like test for the Z axis. It's used to
+ optimize stencil-volume shadow algorithms.
+
+GL_NV_light_max_exponent
+ Lifts the 128 limit for max light exponent.
+
+GL_EXT_texture_rectangle
+ Identical to GL_NV_texture_rectangle
+
+GL_ARB_occlusion_query
+ Useful for visibility-based culling.
+
+GL_ARB_texture_non_power_of_two
+ Removes the restriction that texture dimensions must be powers of two.
+
+GL_ARB_vertex_buffer_object
+ Allows server-side vertex arrays, optimized host/card data transfers, etc.
+
+GL_ARB_point_sprite
+ ARB-approved version of GL_NV_point_sprite. Basically allows textures
+ to be applied to points.
+
+GL_IBM_multimode_draw_arrays
+ Allows multiple vertex arrays to be drawn with one call, including arrays
+ of different types of primitives.
+
+GL_SUN_multi_draw_arrays
+ An alias for GL_EXT_multi_draw_arrays, standard in OpenGL 1.4.
+
+Faster glDrawPixels / glCopyPixels in X11 driver
+ If your X screen is 32bpp, glDrawPixels to the front color buffer will
+ be accelerated (via XPutImage()) if the image format is GL_BGRA and the
+ type is GL_UNSIGNED_BYTE. No raster operations, such as depth test,
+ blend, fog, etc. can be enabled.
+
+ If your X screen is 16bpp, glDrawPixels to the front color buffer will
+ be accelerated (via XPutImage()) if the image format is GL_RGB and the
+ type is GL_UNSIGNED_SHORT_5_6_5. No raster operations, such as depth
+ test, blend, fog, etc. can be enabled.
+
+ glCopyPixels() calls for the front color buffer will be accelerated
+ (via XCopyArea()) if no raster operations, such as depth test, blend,
+ fog, pixel zoom, etc. are enabled.
+
+ The speed-up over typical software rendering is a factor of 10 for
+ glDrawPixels and 100 for glCopyPixels.
+
+
+With the addition of GL_ARB_occlusion_query, GL_ARB_vertex_buffer_object,
+GL_ARB_texture_non_power_of_two and GL_EXT_shadow_funcs, Mesa 5.1 supports
+all the new features of OpenGL 1.5. Mesa 6.0 (the next stable release)
+will advertise GL_VERSION = "1.5".
+
+
+
+Vertex/Fragment program debugger
+--------------------------------
+
+GL_MESA_program_debug is an experimental extension to support
+interactive debugging of vertex and fragment programs. See the
+docs/MESA_program_debug.spec file for details.
+
+The bulk of the vertex/fragment program debugger is implemented
+outside of Mesa. The GL_MESA_program_debug extension just has minimal
+hooks for stopping running programs and inspecting programs.
+
+The progs/tests/debugger.c (only in CVS) program is an example of how
+the extension can be used. Presently, the debugger code and demo code
+is in the same file. Eventually the debugger code should be moved
+into a reusable module.
+
+As it is now, the demo lets you set breakpoings in vertex/fragment
+programs, single step, and print intermediate register values. It's
+basically just a proof of concept.
+
+
+
+Directory tree reorganization
+-----------------------------
+
+The directory structure for Mesa has been overhauled to improve its layout.
+All source code for Mesa, GLU, GLUT, etc is now under the src/ directory
+in appropriate subdirectories.
+
+The Mesa source code and drivers has been reorganized under src/mesa/.
+
+All demonstration programs and tests are now in subdirectories under progs/.
+
+
+
+Build System Changes
+--------------------
+
+The GNU automake/autoconf support has been removed. As it was, it seldom
+worked on anything but Linux. The Mesa developers aren't big fans of
+automake/autoconf/libtool and didn't have the time to maintain it.
+If someone wants to contribute new automake/autoconf support (and is
+willing to maintain it), it may be re-incorporated into Mesa, subject
+to some requirements.
+
+The "old style" makefile system has been updated:
+ 1. Make-config has been trimmed down to fewer, modern configurations.
+ 2. Most of the bin/mklib.* scripts have been rolled into a new "mklib"
+ script that works on all sorts of systems. There are probably some
+ bugs in it, but it's been tested on Linux, SunOS 5.8 and IRIX 6.5.
+ Improvements/contributes are greatly appreciated.
+ 3. The Makefile.X11 files have been cleaned up in various ways
+
+
+
+Source File Changes
+-------------------
+
+The mmath.[ch] files are obsolete. Their contents have been moved
+into the imports.[ch] and macros.[ch] files.
+
+The files related to vertex and fragment programming have changed.
+Old files:
+ vpexec.[ch]
+ vpparse.[ch]
+ vpstate.[ch]
+New files:
+ program.[ch] - generic ARB/NV program code
+ arbprogram.[ch] - ARB program API functions
+ arbfragparse.[ch] - ARB fragment program parsing
+ arbvertparse.[ch] - ARB vertex program parsing
+ arbparse.[ch] - ARB vertex/fragment parsing
+ arbparse_syn.h - vertex/fragment program syntax
+ nvprogram.[ch] - NV program API functions
+ nvvertprog.h - NV vertex program definitions
+ nvfragprog.h - NV fragment program definitions
+ nvvertparse.[ch] - NV vertex program parser
+ nvfragparse.[ch] - NV fragment program parser
+ nvvertexec.[ch] - NV vertex program execution
+ swrast/s_nvfragprog.[ch] - NV fragment program execution
+
+The files related to per-vertex handling have changed.
+Old files:
+ tnl/t_eval_api.c - old per-vertex code
+ tnl/t_imm_alloc.c - old per-vertex code
+ tnl/t_imm_api.c - old per-vertex code
+ tnl/t_imm_debug.c - old per-vertex code
+ tnl/t_imm_dlist.c - old per-vertex code
+ tnl/t_imm_elt.c - old per-vertex code
+ tnl/t_imm_eval.c - old per-vertex code
+ tnl/t_imm_exec.c - old per-vertex code
+ tnl/t_imm_fixup.c - old per-vertex code
+ tnl/t_vtx_sse.c - old per-vertex code
+ tnl/t_vtx_x86.c - old per-vertex code
+New files:
+ tnl/t_save_api.c - new per-vertex code
+ tnl/t_save_loopback.c - new per-vertex code
+ tnl/t_save_playback.c - new per-vertex code
+ tnl/t_vtx_eval.c - old per-vertex code
+
+Other new files:
+ bufferobj.[ch] - GL_ARB_vertex_buffer_object functions
+ version.h - defines the Mesa version info
+
+Other removed files:
+ swrast/s_histogram.[ch] - moved into src/histogram.c
+
+
+
+Other Changes
+-------------
+
+The ctx->Driver.CreateTexture function has been removed - it wasn't used.
+
+New device driver hook functions:
+ NewTextureObject - used to allocate struct gl_texture_objects
+ NewTextureImage - used to allocate struct gl_texture_images
+
+New ctx->Texture._EnabledCoordUnits field:
+ With the addition of GL_NV_fragment_program we may need to interpolate
+ various sets of texture coordinates even when the corresponding texture
+ unit is not enabled. That is, glEnable(GL_TEXTURE_xD) may never get
+ called but we still may have to interpolate texture coordinates across
+ triangles so that the fragment program will get them.
+ This new field indicates which sets of texture coordinates are needed.
+ If a bit is set in the ctx->Texture._EnabledUnits bitmask is set, the
+ same bit MUST be set in ctx->Texture._EnabledCoordUnits.
+
+The ctx->_TriangleCaps field is deprecated.
+ Instead of testing the DD_* bits in _TriangleCaps, you should instead
+ directly test the relevant state variables, or use one of the helper
+ functions like NEED_SECONDARY_COLOR() at the bottom of context.h
+ While testing _TriangleCaps bits was fast, it was kludgey, and setting
+ the bits in the first place could be error prone.
+
+New vertex processing code.
+ The code behind glBegin, glEnd, glVertex, glNormal, etc. has been
+ totally rewritten. It's a cleaner implementation now and should use
+ less memory. (Keith)
+
+
+
+To Do
+-----
+Add screen-awareness to fakeglx.c
+
+
+
+

+ Mesa 6.0 release notes
+
+ January 16, 2004
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 5.1) designate new developmental releases.
+Even numbered versions (such as 6.0) designate stable releases.
+
+Mesa version 6.0 signifies two things:
+
+ 1. A stabilization of the 5.1 development release
+ 2. Implementation of the OpenGL 1.5 specification. When you query
+ glGetString(GL_VERSION) "1.5" will be returned (as long as the
+ driver supports all the required features).
+
+
+Note that the Mesa major version number is incremented with the OpenGL
+minor version number:
+
+ Mesa 1.x == OpenGL 1.0
+ Mesa 2.x == OpenGL 1.1
+ Mesa 3.x == OpenGL 1.2
+ Mesa 4.x == OpenGL 1.3
+ Mesa 5.x == OpenGL 1.4
+ Mesa 6.x == OpenGL 1.5
+
+
+
+New Features
+------------
+
+Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as
+extensions. These extensions were simply promoted to standard features:
+
+ GL_ARB_occlusion_query extension
+ GL_ARB_texture_non_power_of_two extension
+ GL_ARB_vertex_buffer_object extension
+ GL_EXT_shadow_funcs
+
+
+
+Device Drivers
+--------------
+
+Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on
+the device driver. For example, if the driver enables all the ARB
+extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION)
+will return "1.3". Otherwise, it'll return "1.2".
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time. We rely on volunteers to maintain many of the drivers.
+Here's the current status of all included drivers:

+ Mesa 6.1 release notes
+
+ August 18, 2004
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.1) designate new developmental releases.
+Even numbered versions (such as 6.0) designate stable releases.
+
+
+New Features
+------------
+
+Half-precision floating point (GLhalf) pixel formats are supported
+in Mesa, but the feature isn't exposed yet since the ARB extension
+hasn't been finalized yet.
+
+
+Texture image handling
+----------------------
+
+The code which implements image conversion, pixel transfer ops, etc
+for glTexImage commands has been rewritten.
+
+Now the gl_texture_format struct has a new StoreImage function
+pointer. Each texture format must implement this function. The
+function is totally responsible for converting the user's texture
+image into the specific format. A few helper functions makes this
+relatively simple.
+
+Overall, the code is much simpler, cleaner and easier to work with
+now. Adding new texture formats is straight-forward and there's no
+longer any distinction between "hardware" and "software" formats.
+
+Finally, the code for compressed texture images has been reorganized
+as well.
+
+Removed files:
+ texutil.c
+ texutil.h
+ texutil_tmp.h
+
+New files:
+ texcompress_s3tc.c
+ texcompress_fxt1.c
+
+
+
+Driver / context changes
+------------------------
+
+The _mesa_create_context() and _mesa_initialize_context() function
+parameters have changed. They now take a pointer to a struct
+dd_function_table. Drivers can initialize this table by calling
+_mesa_init_driver_functions(). Drivers should then plug in the special
+functions they implement. In particular, the ctx->Driver.NewTextureObject
+pointer _must_ be set so that the default texture objects created in
+_mesa_create/initialize_context() are correctly built.
+
+The _mesa_init_driver_functions() function allows a lot of redundant code
+to be removed from the device drivers (such as initializing
+ctx->Driver.Accum to point to _swrast_Accum). Adding new functions to
+the dd_function_table can be done with less hassle since the pointer can
+be initialized in _mesa_init_driver_functions() rather than in _all_ the
+drivers.
+
+
+Device Drivers
+--------------
+
+Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5
+depending on the device driver's capabilities. For example, if the
+driver enables all the ARB extensions which are part of OpenGL 1.5
+then glGetString(GL_VERSION) will return "1.5". Otherwise, it'll
+return "1.4" or the next lower version that implements all required
+functionality.

+some time. We rely on volunteers to maintain many of the drivers.

+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.1) designate new developmental releases.
+Even numbered versions (such as 6.2) designate stable releases.
+
+
+This release primarily just fixes bugs found in the Mesa 6.1 release.
+See the VERSIONS file for details.
+
+
+ToDo: PBO for polygon stipple, convolution filter, etc.
+
+
+
+Known Issues
+------------
+
+The GL_EXT_pixel_buffer_object extension isn't fully implemented for
+functions like glPolygonStipple, glConvolutionFilter, glColorTable,
+etc. The important functions like glRead/DrawPixels, glTex[Sub]Image,
+and glBitmap work with PBOs.

+ Mesa 6.2.1 release notes
+
+ December 9, 2004
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.1) designate new developmental releases.
+Even numbered versions (such as 6.2.x) designate stable releases.
+
+
+This release primarily just fixes bugs found in the Mesa 6.2 release.
+See the VERSIONS file for details.
+
+
+
+Known Issues
+------------
+
+The GL_EXT_pixel_buffer_object extension isn't fully implemented for
+functions like glPolygonStipple, glConvolutionFilter, glColorTable,
+etc. The important functions like glRead/DrawPixels, glTex[Sub]Image,
+and glBitmap work with PBOs. This has been fixed for Mesa 6.3.

+ Mesa 6.3 release notes
+
+ July 20, 2005
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.3) designate new developmental releases.
+Even numbered versions (such as 6.2) designate stable releases.
+
+
+
+New Features
+------------
+
+GL_ARB_draw_buffers - allows a fragment program to write to a number of
+ separate color buffers, instead of just one.
+
+GL_OES_read_format - allows one to query the fastest glReadPixels format
+ and datatype.
+
+GL_ARB_pixel_buffer_object - buffer objects for pixel read/write functions.
+
+GL_EXT_framebuffer_object - allows render-to-texture and provides a
+ window-system indepedent Pbuffer facility.
+ The Mesa CVS tree contains a couple tests of this extension.
+
+DirectFB driver, contributed by Claudio Ciccani. See docs/README.directfb
+for details.
+
+
+
+Vertex/Fragment Program PRINT Instruction
+-----------------------------------------
+
+The GL_NV_vertex_program and GL_NV_fragment_program languages have been
+extended with a PRINT instruction.
+
+
+
+glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed
+--------------------------------------------------------------------
+
+To match the behaviour of other OpenGL implementations, glDeleteTextures,
+glDeletePrograms and glDeleteBuffers have been modified so that:
+
+ * The named texture/program/buffer ID is immediately freed for re-use.
+
+ * The actual texture object, program or buffers isn't really deleted until
+ it is no longer bound in any rendering context (the reference count
+ is zero).
+
+Previously, the texture/program/buffer ID wasn't freed until the object
+was really deleted.
+
+Note that textures, programs and buffers can be shared by several rendering
+contexts so they can't be deleted until they're unbound in _all_ contexts.
+
+
+
+GL_EXT_framebuffer_object changes
+---------------------------------
+
+Implementing this extension involved changing a lot of code (for the better).
+
+The gl_framebuffer object now a collection of gl_renderbuffer objects.
+Renderbuffers may store colors, stencil indices, or depth values. The
+gl_framebuffer and gl_renderbuffer types are object-oriented in design.
+
+All the old RGB, color index, stencil and depth-related span functions for
+reading/writing pixels from/to buffers has changed. Now, all pixels are
+read/written through a set of common renderbuffer functions (methods).
+
+Most device drivers have been updated for these changes, but some haven't.
+
+
+
+To Do (someday) items
+---------------------
+ Switch to freeglut
+ Increase MAX_DRAWBUFFERS
+ driver hooks for BeginQuery/EndQuery
+
+
+
+Miscellaneous
+-------------
+
+The main/get.c file is now generated with a Python script (get_gen.py).

+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.3) designate new developmental releases.
+Even numbered versions (such as 6.4) designate stable releases.
+
+
+6.4 is a bug-fix release. See the VERSIONS file for details.
+
+
+
+GLUT tarball
+------------
+
+Starting with 6.4, the GLUT library sources are distributed in a separate
+tarball. This was done at the request of Linux distro vendors who prefer
+to use freeglut.
+
+
+
+
+Driver Status
+---------------------- ----------------------
+DRI drivers varies with the driver
+XMesa (Xlib) implements OpenGL 1.5
+OSMesa (off-screen) implements OpenGL 1.5

+Compilation and Installation using Autoconf
+
+
+Basic Usage
+Driver Options
+
+Library Options
+
+Demo Program Options
+
+
+
+
+1. Basic Usage
+
+
+The autoconf generated configure script can be used to guess your
+platform and change various options for building Mesa. To use the
+configure script, type:
+
+
+
+ ./configure
+
+
+
+To see a short description of all the options, type ./configure
+--help
. If you are using a development snapshot and the configure
+script does not exist, type ./autogen.sh
to generate it
+first. If you know the options you want to pass to
+configure
, you can pass them to autogen.sh
. It
+will run configure
with these options after it is
+generated. Once you have run configure
and set the options
+to your preference, type:
+
+
+
+ make
+
+
+
+This will produce libGL.so and several other libraries depending on the
+options you have chosen. Later, if you want to rebuild for a different
+configuration run make realclean
before rebuilding.
+
+
+
+Some of the generic autoconf options are used with Mesa:
+
+
+--prefix=PREFIX
- This is the root directory where
+files will be installed by make install
. The default is
+/usr/local
.
+
+--exec-prefix=EPREFIX
- This is the root directory
+where architecture-dependent files will be installed. In Mesa, this is
+only used to derive the directory for the libraries. The default is
+${prefix}
.
+
+--libdir=LIBDIR
- This option specifies the directory
+where the GL libraries will be installed. The default is
+${exec_prefix}/lib
. It also serves as the name of the
+library staging area in the source tree. For instance, if the option
+--libdir=/usr/local/lib64
is used, the libraries will be
+created in a lib64
directory at the top of the Mesa source
+tree.
+
+--enable-static, --disable-shared
- By default, Mesa
+will build shared libraries. Either of these options will force static
+libraries to be built. It is not currently possible to build static and
+shared libraries in a single pass.
+
+CC, CFLAGS, CXX, CXXFLAGS
- These environment variables
+control the C and C++ compilers used during the build. By default,
+gcc
and g++
are used with the options
+"-g -O2"
.
+
+LDFLAGS
- An environment variable specifying flags to
+pass when linking programs. These are normally empty, but can be used
+to direct the linker to use libraries in nonstandard directories. For
+example, LDFLAGS="-L/usr/X11R6/lib"
.
+
+PKG_CONFIG_PATH
- When available, the
+pkg-config
utility is used to search for external libraries
+on the system. This environment variable is used to control the search
+path for pkg-config
. For instance, setting
+PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig
will search for
+package metadata in /usr/X11R6
before the standard
+directories.
+
+
+
+
+
+There are also a few general options for altering the Mesa build:
+
+--with-x
- When the X11 development libraries are
+needed, the pkg-config
utility will
+be used for locating them. If they cannot be found through
+pkg-config
a fallback routing using imake
will
+be used. In this case, the --with-x
,
+--x-includes
and --x-libraries
options can
+control the use of X for Mesa.
+
+--enable-gl-osmesa
- The OSMesa
+library can be built on top of libGL for drivers that provide it.
+This option controls whether to build libOSMesa. By default, this is
+enabled for the Xlib driver and disabled otherwise. Note that this
+option is different than using OSMesa as the driver.
+
+--enable-debug
- This option will enable compiler
+options and macros to aid in debugging the Mesa libraries.
+
+--disable-asm
- There are assembly routines
+available for a few architectures. These will be used by default if
+one of these architectures is detected. This option ensures that
+assembly will not be used.
+
+--enable-32-bit, --enable-64-bit
- By default, the
+build will compile code as directed by the environment variables
+CC
, CFLAGS
, etc. If the compiler is
+gcc
, these options offer a helper to add the compiler flags
+to force 32- or 64-bit code generation as used on the x86 and x86_64
+architectures.
+
+
+
+
+
+
+2. Driver Options
+
+
+There are several different driver modes that Mesa can use. These are
+described in more detail in the basic
+installation instructions . The Mesa driver is controlled through the
+configure option --with-driver. There are currently three supported
+options in the configure script.
+
+
+
+
+
+Xlib - This is the default mode for building Mesa.
+It uses Xlib as a software renderer to do all rendering. It corresponds
+to the option --with-driver=xlib
. The libX11 and libXext
+libraries, as well as the X11 development headers, will be need to
+support the Xlib driver.
+
+
+
+DRI - This mode uses the DRI hardware drivers for
+accelerated OpenGL rendering. Enable the DRI drivers with the option
+--with-driver=dri
. See the basic
+installation instructions for details on prerequisites for the DRI
+drivers.
+
+
+
+
+
+--with-dri-driverdir=DIR
- This option specifies the
+location the DRI drivers will be installed to and the location libGL
+will search for DRI drivers. The default is ${libdir}/dri
.
+
+--with-dri-drivers=DRIVER,DRIVER,...
- This option
+allows a specific set of DRI drivers to be built. For example,
+--with-dri-drivers="swrast,i965,radeon,nouveau"
. By
+default, the drivers will be chosen depending on the target platform.
+See the directory src/mesa/drivers/dri
in the source tree
+for available drivers. Beware that the swrast DRI driver is used by both
+libGL and the X.Org xserver GLX module to do software rendering, so you
+may run into problems if it is not available.
+
+--disable-driglx-direct
- Disable direct rendering in
+GLX. Normally, direct hardware rendering through the DRI drivers and
+indirect software rendering are enabled in GLX. This option disables
+direct rendering entirely. It can be useful on architectures where
+kernel DRM modules are not available.
+
+--enable-glx-tls
- Enable Thread Local Storage (TLS) in
+GLX.
+
+--with-expat=DIR
- The DRI-enabled libGL uses expat to
+parse the DRI configuration files in /etc/drirc
and
+~/.drirc
. This option allows a specific expat installation
+to be used. For example, --with-expat=/usr/local
will
+search for expat headers and libraries in /usr/local/include
+and /usr/local/lib
, respectively.
+
+
+
+
+
+OSMesa - No libGL is built in this
+mode. Instead, the driver code is built into the Off-Screen Mesa
+(OSMesa) library. See the Off-Screen Rendering
+page for more details.
+
+
+
+
+
+--with-osmesa-bits=BITS
- This option allows the size
+of the color channel in bits to be specified. By default, an 8-bit
+channel will be used, and the driver will be named libOSMesa. Other
+options are 16- and 32-bit color channels, which will add the bit size
+to the library name. For example, --with-osmesa-bits=16
+will create the libOSMesa16 library with a 16-bit color channel.
+
+
+
+
+
+
+
+
+3. Library Options
+
+
+The configure script provides more fine grained control over the GL
+libraries that will be built. More details on the specific GL libraries
+can be found in the basic installation
+instructions .
+
+
+
+
+
+
+4. Demo Program Options
+
+
+There are many demonstration programs in the MesaDemos tarball. If the
+programs are available when ./configure
is run, a subset of
+the programs will be built depending on the driver and library options
+chosen. See the directory progs
for the full set of demos.
+
+
+--with-demos=DEMOS,DEMOS,...
- This option allows a
+specific set of demo programs to be built. For example,
+--with-demos="xdemos,slang"
. Beware that if this option is
+used, it will not be ensured that the necessary GL libraries will be
+available.
+
+--without-demos
- This completely disables building the
+demo programs. It is equivalent to --with-demos=no
.
+
+
+
+
+
+
