I'd get rid of as much math as you can in the repeat loops. Precalculate
your loop vars. But, I think you're pretty much stuck for now with the
solution you have.
We're working on an image external toolset which does this and much
more. But it's not yet ready for primetime ;-)
> Also, I think Chipp has done some work along those lines.
