Does anyone know ... would this bug be in the bindings, or in gtk+ or cairo?
If I understand correctly, this is by design. GtkDrawingArea does not have its own GdkWindow, hence all
GtkDrawingAreas within a GtkWindow share the underlying GdkWindow and thus the GdkDrawingContext and thus the
cairo context. Prior to invoking each draw callback, the shared cairo context is altered so that any drawing
done with it ends up in the right spot.
