profile: rename printFontScale to dpr (device pixel ratio)

Browse source 
The printFontScale is used to scale up fonts (and icons) when
rendering to high-DPI devices. With absolute scaling, this
will also be used to scale the size of different chart
regions, line thickness, etc. Therefore, give it an more
appropriate name. "Device pixel ratio", which is a well
established term, seems to appropriately describe the
concept.
