Enable non-integer device pixel ratio
Work around QPaintDevice::metric's int return type
by adding a new metric that returns a scaled devicePixelRatio.
Choose a scale factor that gives us more than enough
range.
The QPaintDevice::devicePixelRatio() convenience accessor
is public API and can unfortunately not be changed
to return a qreal. Add devicePixelRatioF() which
returns the (unscaled) devicePixelRatio.
Change all call sites of QPaintDevice::devicePixelRatio()
to use QPainDevice::devicePixelRatioF().
