mesa: document known possible deviations from ARB_color_buffer_float

parent f7138a08
Known issues in the ARB_color_buffer_float implementation:
- The alpha test is incorrectly performed before conversion to target format in softpipe and llvmpipe
- Rendering to multiple render targets, some fixed-point, some floating-point, with FIXED_ONLY fragment clamping and polygon smooth enabled may write incorrect values to the fixed point buffers (depends on spec interpretation)
- For fragment programs with ARB_fog_* options, colors are clamped before fog application regardless of the fragment clamping setting (this depends on spec interpretation)
