sounds great to me. porting my code to imagemagick as we speak.
a pluggable system might be in order BEFORE we make a release, as my code
performs 2/9ths WORSE on a non-sse2 enabled machine.

personally, i'd love to see some documentation on the feature file format,
and a "clean reference implimentation". i've overhauled your code, and i
still cant make heads or tails out of some of it. comments would be nice. ;)

i'd be interested in seeing some of this work as well, as my input images
