*sigh*... this continually makes me sad.

I think you should be able to just call
RenderLayer::mapRectToPaintInvalidationBacking and not leak groupedMapping().

I meant to try this in the old selection code and never got around to it.

This change is a refactoring so it should just move code around, not fix some
existing bug. I am happy to follow-up on that!
