    // particularly the possible meanings these names might have in any specializations of Window.

    // For example "state" (meaning windowState) is not a good property to declare, because it has

    // a different meaning in QQuickItem, and users will tend to assume it is the same for Window.

    // C++ properties in qwindow.cpp AND as QML properties in qquickwindow.cpp.
