Merging the UTF8 patch, consisting of O'ksi'd s original 1.1.6 patch …

…and additions by Ian. PLEASE BE AWARE that the patch in its current incarnation is a regression in many aspects and further work is required before we can announce Unicode support.

+NOTES:
+------
+This is a cut down snapshot of fltk-1.1.x-r6041 merged in a somewhat
+haphazard manner with the OksiD UTF-8 patch (for fltk-1.1.6)
+Then some of the UTF functions from FLTK2 were back-ported into the
+mix.
+
+This code has also been modified to implement the XFT support on X
+that was missing from the fltk-1.1.6 variant.
+
+I have also introduced a number of extra test programs into the "demo"
+directory - to test DnD operation, and to verify the behaviour Fl::add_fd()
+on various platforms (this test also verifies some aspects of UDP multicast
+operation that was causing issues on win32 with winsock-1.1.)
+These two examples are accessed from the Demo program in the Events submenu.
+
+There is also an extended font-chooser/unicode font display test, derived
+from the utf8 test that OksiD had added to fltk-1.1.6-utf8.
+This is accessed in the Demo program under the Other Tests/Font Tests 
+submenu.
+
+
+This code has been tested on linux (FC7), WinXP with mingw
+and OSX 10.4.11.
+The OSX port MUST HAVE the QUARTZ mode enabled in configure to
+work (the older fltk QD code will not work.)
+
+
+Linux
+-----
+This code has been built with the following configure options
+on the linux platform:
+
+./configure --enable-threads --enable-xft
+
+At present the code also works without XFT enabled (as the original OksiD 
+code did) but I can't count on that state of affairs being permanent!
+
+./configure --enable-threads
+
+
+WIN32
+-----
+On WinXP, the code was built with mingw in an Msys shell with the
+following configure options:
+
+./configure --enable-threads
+
+Was used an a box that already has image libs installed.
+
+./configure --enable-threads  --enable-localjpeg --enable-localzlib --enable-localpng
+
+Was used an a box that does not have image libs installed.
+
+Both cases function as expected.
+
+I do not have access to the MS compler tools here, so the code is untested with
+their compilers. I do not think I have introduced any incompatabilities but...
+Feedback welcome.
+
+NOTE: The "standard" FLTK-1.1 build uses the (deprecated) winsock-1.1 libs.
+This revised code uses the (allegedly) better winsock-2 libs instead.
+This means you will probably have to change the link options in any existing
+projects to incorporate this change - the libs are *NOT* reliably inter-changeable!
+(fltk-utf8-config will return the correct libs for use.)
+
+
+OSX
+---
+The OSX build was configured with:
+
+./configure --enable-threads --enable-quartz
+
+
+Issues
+------
+At time of writing, the code seems to "work", but there are issues:
+
+- The build is "noisy".
+
+- The gl font handling is not ideal under XFT (but it always was
+  anyway. We need a glXUseXftFont method really, but that doesn't seem
+  to exist...I could try and write one, but time...)
+
+- The xim stuff is still needing work - I'm pretty sure I have broken this
+
+- Input methods under win32? I don't know.
+
+- Input Methods under OSX? No idea.
+
+- The code is now badly formatted in places from all my random
+  cut'n'paste...
