Update of /cvsroot/mplayer/main/libmpcodecs
In directory mail:/var/tmp.root/cvs-serv26484

Modified Files:
	vf.c vf.h vf_crop.c vf_expand.c vf_scale.c 
Log Message:
fix segfaults with slices. support slice rendering into a filter even
when the following filter/vo doesn't support slices. also use unified
vf->dmpi rather than having vf->priv->dmpi duplicated in every filter.
