Optimize QGraphicsViewPrivate::updateRect/updateRegion.
We can do QRect::intersects/contains/operator| faster than QRect
because we can assume the rects are normalized. Another
important factor is our knowledge about the viewport rect, which is
always QRect(0, 0, viewport->width(), viewport->height()).
Auto-tests included.
