PrintLayout: disable the QPainter scaling
This is wrong because we don't really need to scale. We already
have the estimated page dimentions in pixels, so taking the
quotient of the printer DPI and screen DPI and then scaling
(probably up) our rendered widgets via the QPainter introduces
blur (due to the oversampling), and a performance penalty.
By rendering at the exact dimensions we ensure that the widgets
are crisp at a 100% printout.
