When using SFML for input in windowed mode, dragging things off the window creates some weird behavior. This includes window controls being dragged sticking to the mouse cursor until the left mouse button is pressed again.
I fixed it by giving GWEN mouse button released events when the mouse leaves the window for all the mouse buttons. This fix includes the fixes described in issue #63 and issue #62.
