    \class QWindow
    \brief The QWindow class encapsulates an independent window in a Windowing System.

    A window that is supplied a parent become a native child window of
    their parent window.

    Windows can potentially use a lot of memory. A usual measurement is
    width * height * depth. A window might also include multiple buffers
    to support double and triple buffering. To release a windows memory
    resources, the destroy() function.

    \section1 Window and content orientation

    QWindow has reportContentOrientationChange() and
    requestWindowOrientation() that can be used to specify the
    layout of the window contents in relation to the screen. The
    window orientation determines the actual buffer layout of the
    window, and the windowing system uses this value to rotate the
    window before it ends up on the display, and to ensure that input
    coordinates are in the correct coordinate space relative to the
    application.

    On the other hand, the content orientation is simply a hint to the
    windowing system about which orientation the window contents are in.
    It's useful when you wish to keep the same buffer layout, but rotate
    the contents instead, especially when doing rotation animations
    between different orientations. The windowing system might use this
    value to determine the layout of system popups or dialogs.
