Gets the internal scale factor that maps from monitor coordinates
to the actual device pixels. On traditional systems this is 1, but
on very high density outputs this 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 window
where it is better to use gdk_window_get_scale_factor() instead.
