The mapping and unmapping of the X11 stage implementation is a bit bong. It's asynchronous, for starters, when it really can avoid it by tracking the state internally. The ordering of the map/unmap sequence is also broken with respect to the resizing. By tracking the state internally into StageX11 we can safely remove the MapNotify and UnmapNotify X event handling. In theory, we should use _NET_WM_STATE a lot more, and reuse the X11 state flags for fullscreening as well.
