I used to know how convolution works but Ive forgotten. Could you
remind me? (by the way, GEM has a [pix_convolve] object as well)

If I remember correctly, convolution traverses a two-dimentional
array of numbers, and multiplies thoes numbers and their adjacent
values by some lesser dimentioned array...

...Im an artist/computer science major and I only remember this
(proabably flawed) bit if information from a cognitive science
class where they were using convolution as edge detection for
robotic vision.

Again, Thanks for the help!
