Could you extend the test with this other scenario please:

mask1: at depth 1 masks up to layer 6
mask2: at depth 2 masks up to layer 3
maskee: at depth 4

I guess maskee should be masked by mask1 and not mask2.

The test, with both scenarios (maybe in two frames) would
be very helpful to test more things:
        - rendering
        - AS hitTest
        - mouse handling (maskee should do something onRollOver/Out, like 
changing alpha)
        - _droptarget (needs something to drag)
