* that, when we do a RGB <-> RGBX copy, the two formats will line up even
* though one of them is 3/4 the size of the other. The choice of UNORM
* vs. UINT is also very intentional because Haswell doesn't handle 8 or
* 16-bit RGB UINT formats at all so we have to use UNORM there.
* Fortunately, the only time we should ever use two different formats in
* the table below is for RGB -> RGBA blits and so we will never have any
