Due to the many different ways to set factories, it makes sense to expose them as custom objects. This makes the actual APIs for the list widgets simpler, because they can just have a regular "factory" property. As a convenience function, gtk_list_view_new_with_factory() was added to make this whole approach easy to use from C.
