Fixes: Optimize QGraphicsViewPrivate::updateRect()/updateRegion().
Details: Those cut-offs are extremely important. After few seconds
interaction with the iphone demo, updateRect() was called
approx. 3000 times with an empty rect. Then imagine what
happens when having e.g. FullViewportUpdate. We do
q->viewport()->update() JUST FOR FUN!
(cherry picked from commit be6be8c73929f2ddee9a02f59db05c3ba453a63e)
