New Features

OpenGL Shading language support

   This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100,

   GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions.  Most of

   the work was done by Michal Krol.

   There's probably a fair number of bugs since this is a pretty large,

   complicated body of code.

   The OpenGL 2.0 interface to these features will be implemented in a

   future version of Mesa,

GL_EXT_timer_query

   Used to measure the time of OpenGL operations at high precision.

   Only supported in the software/Xlib driver at this time.

GL_EXT_packed_depth_stencil

   Defines a new GL_DEPTH_STENCIL_EXT pixel format.

GL_EXT_framebuffer_blit

   A simplified glCopyPixels-like feature for copying pixel rectangles.

GL_ARB_half_float_pixel

   Adds a new half-precision floating point format for image transfers,

   such as for glDrawPixels, glReadPixels, glTexImage, etc.

Changes

removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead)

removed GL_SGIX/SGIS_pixel_texture extensions

Bug fixes

fixed glxcontextmodes.c datatype problem (bug 5835)

fixed aix-gcc build/install bugs (bug 5874)

fixed some bugs in texture env program generation

glXCopyContext() didn't handle texture object bindings properly

glXCopyContext() didn't copy all lighting state

fixed FreeBSD config (Pedro Giffuni)

fixed some minor framebuffer object bugs

replaced dprintf() with _glu_printf() in GLU (bug 6244)

fixed a number of thread safety bugs/regressions

fixed a number of GLU tesselator bugs (John Shell, bug 6339)

paletted texturing was broken w/ floating point palettes (K. Schultz)

lots of assorted framebuffer object bug fixes

Known Issues

Rendering to depth textures will not work.  Rendering to GL_DEPTH_STENCIL

textures should work.

Driver Interface Changes

Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by

the two-sided versions: Driver.Stencil*Separate().

Render-to-texture: The functions for rendering to textures have changed.

To Do (someday) items

Switch to freeglut

Increase MAX_DRAWBUFFERS

Fix linux-glide target/driver.

Fix lambda calculation for frag progs.
