QQuickWindow FBO: fix dpr and rect when there is an actual window

QQuickWidget is the primary example of a third case of rendering with
QQuickWindow: here the content goes to an FBO via the rendercontrol,
but there is still a window associated (the top-level widget's window)
in a way, and therefore the devicePixelRatio must be taken into account.
