; FIXME(rbultje) the non-bilinear versions (i.e. x=0,8&&y=0,8) are identical
; between the ssse3 and non-ssse3 version. It may make sense to merge their
; code in the sense that the ssse3 version would jump to the appropriate
; location in the sse/2 version, rather than duplicating that code in the
