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 :(((( Originally committed as revision 6604 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
