Turning imageData into alphaData (quickly)?

[Chipp Walters]

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 ;-)

best,

Chipp
