Yeah, not ideal.

I don't use it for images, I have my own solution for that with
supersampling antialising.
But for movie conversion, what is the alternative? I on occasion
- Extract frames, apply remapping in my code for each frame, assemble movie.
- Generate remap filters 2,3 or 4 times larger than I need and scale
result down.
