Patch toward fixing tst_QWidget::windowState().
In QWidget::setWindowState() there was some code to emulate window
states when they're not supported by the backend, by hiding the window
on minimize or using the screen geometry and the frameless window hint
to manually try to make a window fullscreen.
However, some of this code was being run even when the backend does
support setting window states, specifically calling setParent(0) to
force a re-creation of the platform window and calling show(). These led
to the window getting the wrong position after being minimized or
fullscreen and going back to the normal state.
Apart from storing the normal geometry of a widget when going away from
the normal state we shouldn't do any magic when the call to
QPlatformWindow::setWindowState() succeeds.
tst_QWidget::windowState() still fails due to calling move() to set the
position of the widget including the frame, when QWindow currently only
supports setting the position of the widget excluding the frame.
