...there is a pix_perlin in Gem, at least on my harddrive ;-) When
banged, it produces a noise texture of some requested
dimensions...I've always wanted to go ahead and make a [perlin~] or
just a control [perlin], but haven't gotten around to it...
...btw, didn't use libnoise, just adapted some of the many variations
of perlin.c out in the wild...
