-/// \brief This pass maps the pseudo interpolation registers to the correct physical
-/// registers.
-//
-/// Prior to executing a fragment shader, the GPU loads interpolation
-/// parameters into physical registers. The specific physical register that each
-/// interpolation parameter ends up in depends on the type of the interpolation
-/// parameter as well as how many interpolation parameters are used by the
-/// shader.
