Update of /cvsroot/mplayer/main/postproc
In directory mplayer:/var/tmp.root/cvs-serv30699
Modified Files:
swscale.c
Log Message:
MMX & MMX2 optimizations (MMX2 is buggy and commented out)
32, 24, 16, 15 bit support in C (only 32 & 16 tested)
32, 16 bit support in mmx (16 with dithering)
ranges of some variables changed so mmx likes them more
