The de-virtualization gotcha might result in client code not calling QRasterWindow::resizeEvent, which we use for dirty state management after e0eb2818face4ffb7dafd87464f355d4654b7be0. In practice this wasn't an issue, because QPaintDeviceWindow handles paint events by calling markWindowAsDirty first, but we should not rely on this. Instead plumb the resize event to QPaintDeviceWindowPrivate, which QRasterWindow implements and can override the behavior of.
