This doesn't quite achieve what I want as it does not constrain the geometry of the main window. In order to ensure its child has a fixed aspect ratio, the GtkAspectFrame introduces horizontal or vertical padding if its own aspect ratio is different. The ability to provide a geometry widget to gtk_window_set_geometry_hints seems to be designed to solve exactly the problem I'm facing, except it doesn't have the desired effect.
