By setting a filter function on the @box one can decide dynamically
which of the children to show. For instance, to implement a search
function that only shows the children matching the search terms.
The @filter_func will be called for each child after the call, and
it will continue to be called each time a child changes (via
gtk_flow_box_child_changed()) or when gtk_flow_box_invalidate_filter()
is called.
