I have reviewed patch,
and tested with my local test cases.
including margin test, animated text, long lines, huge fonts.

So far so good.

and the performance is as the author said, even in the worst cases,
such as animated text, the performance is slightly better than old one.

One thing to notice, this patch has already merged George's 
"[PATCH] vf_ass: reduce useless up/downsampling." in some degree.
http://article.gmane.org/gmane.comp.video.mplayer.devel/62119

So we only have to patch this one.

Hope it appears in the upstream ASAP.
