--- Comment #2 from Emmanuele Bassi <ebassi at gmail.com> ---
looking around at various sources, it seems that we should do:

  CGContextScaleCTM (cgc, scaleFactor, scaleFactor);

when creating the CGBitmapContext inside cairo_quartz_surface_create(), where
scaleFactor is the device scale factor for the surface.
