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