--- Comment #14 from Jason Ekstrand <jason at jlekstrand.net> ---
Done.  It's nothing like the patch from Ville because we recently completely
rewrote the way you shove that sort of side-band data into the shader.  It's
actually way easier now.

    anv: Emulate texture swizzle in the shader when needed

    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.
