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.
Build System Changes
--------------------
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
NOTE: there are plans to completely reorganize the Mesa directory tree
structure. At that time, the GNU autoconf/autoconfig support will be
removed.

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.
To Do
-----
Add screen-awareness to fakeglx.c
