Compositor: Skip unnecessary background fill

Hello all,

As  Tim-Philipp commented the patch could re-use the just-introduced
is_rectangle_contained() function. This new version do it.

Maybe the decision if background is necessary or not could be taken into
prepare_frame(), but I do not know if it will be any performance benefits and I
think right now it is more clear.

Pablo.
