Original commit message from CVS: * gst/deinterlace2/tvtime/tomsmocomp/SearchLoopBottom.inc: * gst/deinterlace2/tvtime/tomsmocomp/SearchLoopTop.inc: * gst/deinterlace2/tvtime/tomsmocomp/StrangeBob.inc: * gst/deinterlace2/tvtime/tomsmocomp/WierdBob.inc: Unroll the loop to handle two bytes at once. This should give a small speedup and makes it possible to handle chroma and luma different which is needed later.
