     * a non-client of the input method framework.

     * <p>
     * If <code>isFullScreenSupported</code> returns
     * <code>false</code>, full-screen exclusive mode is simulated by resizing
     * the window to the size of the screen and positioning it at (0,0).

     * When returning to windowed mode from an exclusive full-screen window, any
     * display changes made by calling <code>setDisplayMode</code> are
