sRGB dxgi formats support?

[Zelex]

It appears as though BC1_UNORM vs BC1_UNORM_SRGB decode 100% identically.

Pretty sure that should be a bug?

Also, it seems I cannot attach DDS files to issues =/ Though thats a github issue, not your issue per-se. let me know if you want some test files. I can email some no problem.

I'm going to link #277 because they're really the same issue. This problem is really annoying because it means that you have to know the context that an image is going to be used in before loading it - BC7_UNORM images have to be loaded as BC7_UNORM_SRGB images when used for colour data. It's a pretty simple fix, just use a flag that sets whether a _SRGB format is set or not.
