[PATCH 2/3] xwayland: Shape window region to clip shadow area from input

[Scott Moreau]

Decorated windows were getting the size of the window including the
shadow which is correct, but causing some confusion for motion input
events. This was exhibited when one xwayland window overlaps another,
hovering over the window beneath recieves no events if within the 32
pixel shadow border area of the window above.
