	* src/stack.c (window_is_fullscreen_size): When checking if a
	window is fullscreen size, only require it to be at the origin
	of the work area, not at the origin of the screen/xinerama.
	Still require it to be full screen in width x height.
	May fix xine in the case where the user has a top panel.

	* src/window.c (constrain_position): restore the ability for
	undecorated windows to position themselves overlapping the top
	panel, but don't let decorated windows do so. Oh the hacks...
