start supporting nested boxes

Box decorations have priority over box insides. If a click is on a move or resize affordance, that takes priority over it also being inside a box.

When a click is inside two boxes the innermost box takes precedence.

If the boxes merely overlap and it's unclear that one is wholly within the other, then we continue to throw up our hands and return unpredictable results.

This one small change already feels quite nice for nested boxes!
