[Mesa-dev] [PATCH 3/4] i965: Add support for MESA_FORMAT_RGB_FLOAT32 surfaces.

[Eric Anholt]

This is for GL_ARB_texture_buffer_object_rgb32 support, but it also
causes the format to get used for float32 rgb textures as well on
Ironlake and later.  Since that came with some surprises, separate
the change from the enable commit.
