* appear beneath the full-screen window in the Z-order.
* <li>There can be only one full-screen window on a device at any time, so calling this method

* to return to windowed mode.
* <li>Input method windows are disabled. It is advisable to call <code>
* Component.enableInputMethods(false)</code> to make a component a non-client of the input
* method framework.
* </ul>
*
* <p>Simulated full-screen mode resizes the window to the size of the screen and positions it at
* (0,0).
*
* <p>When entering full-screen mode, if the window to be used as a full-screen window is not
* visible, this method will make it visible. It will remain visible when returning to windowed
* mode.
*

* shape is set to {@code null}, the opacity value is set to 1.0f, and the background color alpha
* is set to 255 (completely opaque). These values are not restored when returning to windowed
* mode.

* made by calling {@code setDisplayMode} are automatically restored to their original state.
*
* @param w a window to use as the full-screen window; {@code null} if returning to windowed mode.
