Hmm. That might work well I think. Cool!
Ah.. one other comment...
I'm not sure if it'd be faster to just cycle through all the pixels
within the intersected area until you hit one that proved that there
was a pixel on.. I suppose in the worst case, then you might end up
going through all the intersected region...
