You could put the gtkcairo widget inside a gtk_aspect_frame
and then remove scale_for_aspect_ratio()
- let gtk maintain the gtkcairo widget with the correct aspect ratio,
and just scale to fit the widget width and height, without needing
to use cairo_translate() to offset into the gtkcairo window, patch
attached.

(I'm not sure how this would interact with ']' scale-by-x1.25, and do
not understand why you would want to define a key to do this when you
can manually resize the window anyway)
