0012  * Small test application to test the difference between unmap and destroy.
0013  * The window has two buttons: one called "Unmap" which will hide() the QWindow,
0014  * one called "Destroy" which will close() the QWindow.
0015  *
0016  * The test application can be run with qmlscene:
0017  *
0018  * @code
0019  * qmlscene unmapdestroytest.qml
0020  * @endcode
0021  *
0022  * In order to test different modes, the test application understands some arguments:
0023  * --unmanaged    Creates an override redirect window
0024  * --frameless    Creates a frameless window (comparable Plasma Dialog)
