Improve widget painting under dpr>1 by enabling smooth pixmap scaling
Smooth scaling of icons etc. give far better visual results,
particularly with fractional dpr scaling. So enable this generally in
QStylePainter, and make more of the relevant widgets use QStylePainter
instead of QPainter directly.
Differences can be seen in the widgets examples, e.g. textedit,
gallery, stylesheet (Pagefold), mdi.
