[Michael Niedermayer]

Update of /cvsroot/mplayer/main/postproc
In directory mplayer:/var/tmp.root/cvs-serv25165

Modified Files:
	rgb2rgb.c rgb2rgb_template.c rgb2rgb.h 
Log Message:
byte interleaving for mga
untested (no g200 mga or whatever i would need ...)
experimental sse2 version (even less tested as no p4 either ...)
sse2 version would need 16-byte aligned src & dst else sig11
sse2 version is disabled by default
