Yeah, that would be cool. I'd call that "reimplementing the fractal 
generator in SDL." :-)

I just spent about 10 times as long as I spent on the original program, 
trying to get a second fractal that can patch into the middle of the 
first fractal with the edges lined up, and it has me completely stumped 
why all the numbers come out right but the actual picture looks wrong. 
Edges don't line up, jaggies poke way out of the way, etc. :-) Moving on 
to something else for the moment...

(If anyone wants the code as it stands, I can post it, but it's not 
POV-specific.)
