Catalyst GL 4.4 bindless texture ignores srgb

Hi,

I implemented partial azdo technic in our open source game whose next version is likely to be released this month.

It's not enabled by default.

From catalyst 14.3 beta (where it was introduced) arb bindless textures doesn't honor the srgb status of texture. GL_SRGB textures are sampled as GL_RGB texture.

I workarounded this with a pow(., 2.2) call but I would prefer to avoid an extra instruction.
