+ Only works with 2D, 2D array, cubemaps, and cubemaps arrays.
+ For 2D textures, only the addressing modes of the sampler and

+ to filtering are placed into xyzw in clockwise order,
+ starting with the (u,v) texture coordinate delta at the
+ following locations (-, +), (+, +), (+, -), (-, -), where
+ the magnitude of the deltas are half a texel.

+ PIPE_CAP_TEXTURE_SM5 enhances this instruction to support
