	 *
	 * This reference will keep pointing to the node pointed to
	 * by @path, so long as it exists. If @path isn’t a valid
	 * path in @model, then %NULL is returned. However, unlike
	 * references created with gtk_tree_row_reference_new(), it
	 * does not listen to the model for changes. The creator of
	 * the row reference must do this explicitly using
	 * gtk_tree_row_reference_inserted(), gtk_tree_row_reference_deleted(),
	 * gtk_tree_row_reference_reordered().
	 *
	 * These functions must be called exactly once per proxy when the
	 * corresponding signal on the model is emitted. This single call
	 * updates all row references for that proxy. Since built-in GTK+
	 * objects like #GtkTreeView already use this mechanism internally,
	 * using them as the proxy object will produce unpredictable results.
	 * Further more, passing the same object as @model and @proxy
	 * doesn’t work for reasons of internal implementation.
	 *
	 * This type of row reference is primarily meant by structures that
	 * need to carefully monitor exactly when a row reference updates
	 * itself, and is not generally needed by most applications.
	 *
	 * Params:
	 *     proxy = a proxy #GObject
	 *     model = a #GtkTreeModel
