New Features
------------
-GL_EXT_timer_query - used to get elapsed time information from the renderer.
+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.
-GL_EXT_packed_depth_stencil - defines a new GL_DEPTH_STENCIL_EXT pixel format.
+ The OpenGL 2.0 interface to these features will be implemented in a
+ future version of Mesa,
-GL_EXT_framebuffer_blit - simplified glCopyPixels-like feature
+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.
-Known Issues
-------------
+GL_ARB_half_float_pixel
+ Adds a new half-precision floating point format for image transfers,
+ such as for glDrawPixels, glReadPixels, glTexImage, etc.
-Rendering to depth or depth/stencil textures will not work, results in
-failed assertions, etc.
+Removed Extensions
+------------------
-Driver Interface Changes
-------------------------
+The following extensions have been removed:
-Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
-the two-sided versions: Driver.Stencil*Separate().
+ GL_HP_occlusion_test - this is superceded by GL_ARB_occlusion_query.
-To Do
------
-Fix linux-glide target/driver.
-Fix lambda calculation for frag progs.
+Known Issues
+------------
+Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL
+textures should work.

Driver Status
---------------------- ----------------------
DRI drivers varies with the driver
-XMesa (Xlib) implements OpenGL 1.5
+XMesa/GLX (on Xlib) implements OpenGL 1.5
OSMesa (off-screen) implements OpenGL 1.5
Glide (3dfx Voodoo1/2) implements OpenGL 1.3
SVGA implements OpenGL 1.3

New:
+ - OpenGL Shading Language support through GL_ARB_shader_objects,
+ GL_ARB_shading_language_100, GL_ARB_vertex_shader and
+ GL_ARB_fragment_shader (done by Michal Krol)
- GL_EXT_packed_depth_stencil extension
- GL_EXT_timer_query extension
- GL_EXT_framebuffer_blit extension
+ - GL_ARB_half_float_pixel
- reflect demo improved to support multiple windows
- singlebuffer demo (shows no/little-flicker single-buffered rendering)
- r200: enable GL_ARB_texture_env_crossbar, separate the texture
- 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
