Returns the internal scale that maps from surface coordinates
to the actual device pixels.
When the scale is bigger than 1, the windowing system prefers to get
buffers with a resolution that is bigger than the surface size (e.g.
to show the surface on a high-resolution display, or in a magnifier).

Compare with gdk.surface.Surface.getScaleFactor, which returns the next larger integer.
The scale may change during the lifetime of the surface.
