Feature suggestion: Bilinear filtering

[oli3012]

This is not an issue per-se, but the lack of filtering introduces aliasing and could be improved by adding bilinear or other form of filtering.

In any case, thanks for sharing this library, it's really helpful!

I'm working on a programme that throws an exception while running since the face image is 4096x4096 in size. I believe the problem is in the transform function; could you check that?
