Martin Gräßlin 5d5673ebc0 Fix rendering errors of close window button in Present Windows
Hiding and Showing the close window button all the time can result in
the window not having a proper content. To fix this issue we keep the
window around, but just don't show it. For this the CloseWindowView
inherits from QObject and delegates the needed calls to the nested
QQuickView.
