[Mesa-dev] [PATCH v2 00/12] Improve integer texture support & add i965 texture_rgb10_a2ui support

[Jordan Justen]

Some test results on i965
--
piglit quick fbo_integer_readpixels_sint_uint: fail => pass
oglconform int-textures basic.clamping.int: fail => pass
oglconform packed-px-uint: skip => 74 of 89 passing

v2:
 * Add glformats.c/glformats.h
 * Move integer texture clamping fixes from ReadPixels to CopyTexSubImage
 * updated docs/GL3.txt for i965 & texture_rgb10_a2ui
 * Fix ugly pseudo-template in .h. I just duplicated the code and dropped
   pack_int_cases_tmp.h.

v1:
 * Improve integer texture support
 * Add i965 texture_rgb10_a2ui support

Jordan Justen (12):
  mesa: add glformats integer type/format detection routines
  mesa pack: use _mesa_problem instead of assert
  mesa unpack: use _mesa_problem rather than assert
  mesa formats: unpack ARGB8888/XRGB8888
  mesa pack: handle uint and int clamping properly
  mesa pack: handle packed integer formats with clamping
  ReadPixels: handle signed/unsigned integer clamping
  mesa GetTexImage: handle signed/unsigned integer clamping
  mesa texstore: handle signed/unsigned integer clamping
  meta: allow CopyTexSubImage on integer formats
  mesa formats: add MESA_FORMAT_ABGR2101010_UINT
  i965: add ARB_texture_rgb10_a2ui support
