+Artistic License 2.0
+Copyright (c) 2000-2006, The Perl Foundation.
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+Preamble
+This license establishes the terms under which a given free software
+Package may be copied, modified, distributed, and/or redistributed. The
+intent is that the Copyright Holder maintains some artistic control over
+the development of that Package while still keeping the Package
+available as open source and free software.
+
+You are always permitted to make arrangements wholly outside of this
+license directly with the Copyright Holder of a given Package. If the
+terms of this license do not permit the full use that you propose to
+make of the Package, you should contact the Copyright Holder and seek a
+different licensing arrangement.
+
+Definitions
+"Copyright Holder" means the individual(s) or organization(s) named in
+the copyright notice for the entire Package.
+
+"Contributor" means any party that has contributed code or other
+material to the Package, in accordance with the Copyright Holder's
+procedures.
+
+"You" and "your" means any person who would like to copy, distribute, or
+modify the Package.
+
+"Package" means the collection of files distributed by the Copyright
+Holder, and derivatives of that collection and/or of those files. A
+given Package may consist of either the Standard Version, or a Modified
+Version.
+
+"Distribute" means providing a copy of the Package or making it
+accessible to anyone else, or in the case of a company or organization,
+to others outside of your company or organization.
+
+"Distributor Fee" means any fee that you charge for Distributing this
+Package or providing support for this Package to another party. It does
+not mean licensing fees.
+
+"Standard Version" refers to the Package if it has not been modified, or
+has been modified only in ways explicitly requested by the Copyright
+Holder.
+
+"Modified Version" means the Package, if it has been changed, and such
+changes were not explicitly requested by the Copyright Holder.
+
+"Original License" means this Artistic License as Distributed with the
+Standard Version of the Package, in its current version or as it may be
+modified by The Perl Foundation in the future.
+
+"Source" form means the source code, documentation source, and
+configuration files for the Package.
+
+"Compiled" form means the compiled bytecode, object code, binary, or any
+other form resulting from mechanical transformation or translation of
+the Source form.
+
+Permission for Use and Modification Without Distribution
+(1) You are permitted to use the Standard Version and create and use
+Modified Versions for any purpose without restriction, provided that you
+do not Distribute the Modified Version.
+
+Permissions for Redistribution of the Standard Version
+(2) You may Distribute verbatim copies of the Source form of the
+Standard Version of this Package in any medium without restriction,
+either gratis or for a Distributor Fee, provided that you duplicate all
+of the original copyright notices and associated disclaimers. At your
+discretion, such verbatim copies may or may not include a Compiled form
+of the Package.
+
+(3) You may apply any bug fixes, portability changes, and other
+modifications made available from the Copyright Holder. The resulting
+Package will still be considered the Standard Version, and as such will
+be subject to the Original License.
+
+Distribution of Modified Versions of the Package as Source
+(4) You may Distribute your Modified Version as Source (either gratis or
+for a Distributor Fee, and with or without a Compiled form of the
+Modified Version) provided that you clearly document how it differs from
+the Standard Version, including, but not limited to, documenting any
+non-standard features, executables, or modules, and provided that you do
+at least ONE of the following:
+
+(a) make the Modified Version available to the Copyright Holder of the
+Standard Version, under the Original License, so that the Copyright
+Holder may include your modifications in the Standard Version.
+(b) ensure that installation of your Modified Version does not prevent
+the user installing or running the Standard Version. In addition, the
+Modified Version must bear a name that is different from the name of the
+Standard Version.
+(c) allow anyone who receives a copy of the Modified Version to make the
+Source form of the Modified Version available to others under
+(i) the Original License or
+(ii) a license that permits the licensee to freely copy, modify and
+redistribute the Modified Version using the same licensing terms that
+apply to the copy that the licensee received, and requires that the
+Source form of the Modified Version, and of any works derived from it,
+be made freely available in that license fees are prohibited but
+Distributor Fees are allowed.
+Distribution of Compiled Forms of the Standard Version or Modified
+Versions without the Source
+(5) You may Distribute Compiled forms of the Standard Version without
+the Source, provided that you include complete instructions on how to
+get the Source of the Standard Version. Such instructions must be valid
+at the time of your distribution. If these instructions, at any time
+while you are carrying out such distribution, become invalid, you must
+provide new instructions on demand or cease further distribution. If you
+provide valid instructions or cease distribution within thirty days
+after you become aware that the instructions are invalid, then you do
+not forfeit any of your rights under this license.
+
+(6) You may Distribute a Modified Version in Compiled form without the
+Source, provided that you comply with Section 4 with respect to the
+Source of the Modified Version.
+
+Aggregating or Linking the Package
+(7) You may aggregate the Package (either the Standard Version or
+Modified Version) with other packages and Distribute the resulting
+aggregation provided that you do not charge a licensing fee for the
+Package. Distributor Fees are permitted, and licensing fees for other
+components in the aggregation are permitted. The terms of this license
+apply to the use and Distribution of the Standard or Modified Versions
+as included in the aggregation.
+
+(8) You are permitted to link Modified and Standard Versions with other
+works, to embed the Package in a larger work of your own, or to build
+stand-alone binary or bytecode versions of applications that include the
+Package, and Distribute the result without restriction, provided the
+result does not expose a direct interface to the Package.
+
+Items That are Not Considered Part of a Modified Version
+(9) Works (including, but not limited to, modules and scripts) that
+merely extend or make use of the Package, do not, by themselves, cause
+the Package to be a Modified Version. In addition, such works are not
+considered parts of the Package itself, and are not subject to the terms
+of this license.
+
+General Provisions
+(10) Any use, modification, and distribution of the Standard or Modified
+Versions is governed by this Artistic License. By using, modifying or
+distributing the Package, you accept this license. Do not use, modify,
+or distribute the Package, if you do not accept this license.
+
+(11) If your Modified Version has been derived from a Modified Version
+made by someone other than you, you are nevertheless required to ensure
+that your Modified Version complies with the requirements of this
+license.
+
+(12) This license does not grant you the right to use any trademark,
+service mark, tradename, or logo of the Copyright Holder.
+
+(13) This license includes the non-exclusive, worldwide, free-of-charge
+patent license to make, have made, use, offer to sell, sell, import and
+otherwise transfer the Package with respect to any patent claims
+licensable by the Copyright Holder that are necessarily infringed by the
+Package. If you institute patent litigation (including a cross-claim or
+counterclaim) against any party alleging that the Package constitutes
+direct or contributory patent infringement, then this Artistic License
+to you shall terminate on the date that such litigation is filed.
+
+(14) Disclaimer of Warranty: THE PACKAGE IS PROVIDED BY THE COPYRIGHT
+HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR IMPLIED
+WARRANTIES. THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
+PARTICULAR PURPOSE, OR NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT

+OR CONTRIBUTOR WILL BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR
+CONSEQUENTIAL DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE,
+EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

+
+This work follows Stefan Gustavson's paper "Simplex noise demystified"
+http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf
+without using uniform arrays or texture engines.
+
+A single vec4 uniform 'pParam' is used to set the length and a and
+c constants respectively of the permutation polynomial to use. The
+last element of the vec4 is the number of gradients to select from
+on the vertices. An example vec4 is ( 19*19, 2*19, 1, 7 )
+
+Refer to http://en.wikipedia.org/wiki/Permutation_polynomial for
+more information on permutation polynomials.
