[Mesa-dev] [PATCH 10/11] i965: Use native RGB_FLOAT16 support when available.

[Eric Anholt]

Previously we would expand it to RGBA_FLOAT16.  This format now comes out
as framebuffer incomplete, but it seems worth the memory savings if that's
what people are asking for (and GL3 does list it under "texture-only"
color formats)
