    GtkWindow: draw the frame and shadow even for app-paintable windows
    
    If a window is decorated, we need to draw the frame and shadow, even if
    it is app-paintable - it's just nonsense to have a frame that we handle
    events on, but expect the app to paint it. (We paint the titlebar in
    any case.) If a client wants to handle all painting, it should use an
    undecorated window.
