Those values must be scaled to device coordinates - otherwise borders,
margins etc. will be too small when rendered on high dpi devices
(printers etc.).
This change will add the scaling to those values.
QTextDocument::print applies 2cm margins to the root frame of a
unpaginated QTextDocument. Those margins were previously scaled to
device coordinates in order to give the correct result. But because
scaling is now done inside QTextDocumentLayout that scaling must be
removed and pixel values based on qt_defaultDpi are provided instead.
