scipy.ndimage filters

This looks pretty interesting; once things are working a bit better I might investigate a way of inserting filters like this into the render queue somehow.

Hmm, that kind of math looks pretty alien to me :-)

I was thinking that maybe numpy could be interesting for matrix
manipulation, instead of handing it to Cairo. OTOH, i think that
Francesco tried this and that it actually became slower...

The maths looks alien to me too, I was kind of thinking of taking the filters people
had made already as a start.

Not entirely sure how to do them clipped to a path (I guess could use cairo masks somehow).

Yes, I had actually a branch with transform matrix handled by numpy, but
it didn't look too promising: it was slower than the cairo one we had at
that time, though I must admit I am not probably very clever with numpy,
and maybe there was some wiser trick I didn't think of :)

I think numpy might be better when you want to transform a whole load of matrices in one go.
