So, draw that intersected area of the icon into an NSImage that is 1x1

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...
