Gets the internal scale factor that maps from monitor coordinates
to device pixels.
On traditional systems this is 1, but on very high density outputs
it can be a higher value (often 2).
This can be used if you want to create pixel based data for a
particular monitor, but most of the time you’re drawing to a surface
where it is better to use gdk.surface.Surface.getScaleFactor instead.
