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
