Let's have this iterate over children too, to do a
really simple nested-rectangle hit test, that will
allow for fully unit-testing the Windows API

SG.  This impl isn't perfect and will not be able to test for all things.  I
suspect we can just follow up if we need to test things that are more
complicated.
