.. opcode:: GATHER4 - Gathers the four texels to be used in a bi-linear
filtering operation and packs them into a single register.
Only woth with 2D, 2D array, cubemaps, and cubemaps arrays.
Only works with 2D, 2D array, cubemaps, and cubemaps arrays.
For 2D textures, only the addressing modes of the sampler and
the top level of any mip pyramid are used. Set W to zero.
It behaves like the SAMPLE instruction, but a filtered
sample is not generated. The four samples that contribute
to filtering are places into xyzw in cunter-clockwise order,
to filtering are placed into xyzw in counter-clockwise order,
starting with the (u,v) texture coordinate delta at the
following locations (-, +), (+, +), (+, -), (-, -), where
the magnitude of the deltas are half a texel.
