The patch looks good to me. 

But it reminds me of something I've been planning to ask here for some
time now: 

Wouldn't it be easier/cleaner if sRGB sampling/rendering support was not
done through formats, but through enable/disable bits in

I know that DX9 has it as a state, DX10 doesn't even have SRGB anywher
-- I suppose it has to handed in the shaders.

How does the recent hardware cope with this? different RGB/sRGB formats,
sampling/rendertarget state, or shader instruction?
