Set operations on NSBezierPath would definitely help.
If it were *my* program, I think I'd just use an overlay window; that way you can draw what you please and you don't have to worry about what WebKit (or some plug-in) may or may not be doing. FWIW, rectangle intersections are pretty easy (just draw the cases on a piece of paper and you'll see what I mean). General Boolean ops are a *much* harder problem, but you *really* don't need that for what you're doing.
