Now that we have the descriptor buffer mechanism, emulated texture swizzle can be implemented in a very non-invasive way. Previous attempts all tried to extend the push constant based image param mechanism which was gross. This could, in theory, be done much faster with a magic back-end instruction which does indirect MOVs but Vulkan on IVB is already so slow this isn't going to matter much.
