-- A Gtk_Aspect_Frame is the same type of widget as a frame, but it
-- constrains its child to a specific aspect ratio between its width and its
-- height.
--
-- This ratio can either be given explicitly by the user, or chosen from the
-- widget's initial size request (might be different from the one if was
-- actually given).
