* we stomp everything to UINT anyway. The one thing we have to be
* careful of is clear colors. Because fast clear colors for sRGB on
* gen9 are encoded as the float values between format conversion and
* sRGB curve application, a given clear color float will convert to the
* same bits regardless of whether the format is UNORM or sRGB.
* Therefore, we can handle sRGB without any special cases.
