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- Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by the two-sided versions: Driver.Stencil*Separate().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.
