Note that you don't want a window to skip over a solid area during
drag:

In the situation above you shouldn't be able to drag a window from
postion A to position B even though both positions are legal.

Maybe this could be computed by computing the line of window
rectangles between the two positions, and if they are all inside the
non-strut-covered region, the drag is allowed, otherwise it isn't.
