OK so it seems there are some interests for those filters. I was told to
bother only about spp, but I guess that's not enough. So OK, patch
dismissed for now.

Though, I've actually never used most of those filters, and that's true
for a lot of filters I've been porting from libmpcodecs so far. So if
people interested in them could give a hand on porting the latest dozen of
remaining filters, that would be extremely appreciated. I don't think our
current mp lavfi porting workforce will have enough motivation to tackle
this to an end.
