But with ordinary rectangles (with sides parallel
to the axes), if you can extract their
coordinates/size, the analytical problem is trivial:
use this info to get the overlap along each axis.
If the rectangles share a common transform,
this is still pretty easy. So you may be able
to avoid a more general solution.
I've interpreted the question one way: "covered"
might suggest you additionally need the z-order.
