It can be useful to bind the children list to set of objects inside a
GListModel implementation; the GListModel stores the objects, and every
time the model changes, a function is called that maps each object in
the model to a newly created ClutterActor, which is then added as a
child. This API, along with the property binding one inside GObject,
allows automatic creation of views based on object models that update
themselves without manual intervention.
