Subject: [PATCH] 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.
