I was curious as to which implementation it was actually using while I was
porting, and I just forgot to take it out I guess.vf_gradfun, as I wrote it
in MPlayer, can and does use direct rendering.

The only part missing from this code is the part that tells libavfilter that

How would I implement that in the context of this code?
