[Somewhere down here is where the logic to only draw the region of the frame which

draw the applicable region of the rectangle we're on, then unify it with (if
applicable) the higher union.] <-- Possibly obsolete comment, not sure.
I think I might have landed on an alternative solution involving more rearranging
of the storage of the FrameContainers, based on their z-index. Not sure how far
I got with that or if it worked either. See also abi bug 7664 and the original
discussions about defining the undefinedness of layered frame behaviour.
