Guess you're talking about NumPy -- PIL supports 2D convolutions, but
the current version only provides a number of predefined kernels (to be
fixed some day).  And are you sure there's no inverse FFT in NumPy?
I'm 98% sure I've seen people using it...

If noone here can answer this (David?), check with the folks on the
matrix-sig. After all, that's where you find the NumPy experts.
