Retrieves the minimum and natural size of a widget, taking
into account the widget's preference for height-for-width management.
This is used to retrieve a suitable size by container widgets which do
not impose any restrictions on the child placement. It can be used
to deduce toplevel window and menu sizes as well as child widgets in
free-form containers such as GtkLayout.
Note
Handle with care. Note that the natural height of a height-for-width
widget will generally be a smaller size than the minimum height, since the required
height for the natural width is generally smaller than the required height for
the minimum width.
Use gtk_widget_get_preferred_size_and_baseline() if you want to support
baseline alignment.
