we need to have a ::children property on containers then,
and what type should that have? (since we haven't wrapped
GList in the type system, we could just use GValueArray which
is somewhat overkill).
a better idea might be a ::n_children property, however,
that would cost an int in GtkContainer and count composites as well.
