Options

Implement sRGB texture sampling.

Previously sRGB data was converted to linear space on upload. This caused a loss of precision. This change performs the conversion after texel lookup. Note that we had a code path for performing the conversion after filtering, but that leads to failures in dEQP and unacceptable darkening between texels. Also, glTexSubImage calls can update sRGB textures using a format/type combination with no indication of the color space, which caused an unintentional conversion on upload. Likewise we were missing support for an A2B10G10R10UI implementation format.
