That seems to pertain to the gtk_widget_get_preferred_height_for_width
() and gtk_widget_get_preferred_width_for_height () functions which I
understand.

What I'm not clear on is the meaning of the 'natural' arguments in
calls to gtk_widget_get_preferred_height () and
gtk_widget_get_preferred_width ().

Are the natural sizes just some sort hint to containers which may
result in more aesthetically pleasing layouts than just going by the
minimum sizes alone?
