o.k. I've fixed this problem, the distortion was being created by some
code I hadn't completely eliminated when I inlined what was a function
call to speed the program up.

it also tells you how long it took to generate the image on your
machine(I don't remember if that was in the code when I upped it last
night, but it's there now). I'm curious as to how fast it runs on other
machines. it takes 2 minutes 41 seconds at 800x600 with a max of 240
itterations per point on mine (amd 5x86-133 (speed <p90 but >p83 w/o
mmx) w/16-megs) while running it as a dos prog under win95.
