[Mplayer-cvslog] CVS: main/postproc cs_test.c,NONE,1.1 Makefile,1.5,1.6

[Michael Niedermayer]

Update of /cvsroot/mplayer/main/postproc
In directory mail:/var/tmp.root/cvs-serv678

Modified Files:
	Makefile 
Added Files:
	cs_test.c 
Log Message:

colorspace converter tests (memory corruption tests at different width/src/dst)
quite impressive results only 1 of the 13 rgb->rgb converters fails for the c versions
... sadly only 1 of the mmx converters passes though :( ... i feared allready  that last mplayerxp merge reversed the bugfixes :((((
