By setting a sort function on the @box, one can dynamically
reorder the children of the box, based on the contents of
the children.
The @sort_func will be called for each child after the call,
and will continue to be called each time a child changes (via
gtk_flow_box_child_changed()) and when gtk_flow_box_invalidate_sort()
is called.
Note that using a sort function is incompatible with using a model
(see gtk_flow_box_bind_model()).
