Problem description: if a window decoration is in the screenedge (not really unlikely for maximized windows) we either did not get mouse events to the decoration or the screenedge window. E.g. the enter event didn't reach the approach window which means it doesn't get unmapped and thus the motion events in that area are not passed to the decoration below. The same happened for the screenedge window, the enter event was just not delivered if there is a window decoration in the edge. To solve this problem we listen for motion events in the approach and the edge window and pass them from the event filter to the screen edges. If one of our windows contains that the position of the motion event we trigger the edge just in the same way as we do with the enter event.
