The PDF print engine depends on getting unscaled glyphs and some
metrics from the font engine, and for DirectWrite, we were relying
on the superclass implementations of the functions in question,
giving us approximated values. This caused glyphs to be slightly
the wrong size when the DirectWrite engine was in use, e.g. when
high-dpi scaling is enabled.
[ChangeLog][QtPrintSupport][Windows] Fixed glitches in generated
PDFs when the DirectWrite backend was in use, e.g. when high-dpi
scaling was active.
