[Mesa-dev] [PATCH] mesa: fix glGetTexImage for srgb textures when srgb decode is skipped

[Brian Paul]

I think another approach would be to temporarily set the
Sampler.sRGBDecode field to GL_SKIP_DECODE_EXT, use the non-sRGB path
to get the texels, then restore Sampler.sRGBDecode to its original
value.  Call _mesa_set_fetch_functions() as needed to choose the
non-decoding texel fetch functions.  Then we could avoid the
linear_to_nonlinear() function altogether.

We should probably have a piglit test to exercise glGetTexImage with
sRGB textures...
