It is possible to iterate over all the ClutterPathNodes
    inside a ClutterPath by using clutter_path_get_nodes(), which will return
    a GSList of ClutterPathNodes; or by using clutter_path_foreach()
    with a function.
The function pointer passed to clutter_path_foreach() should have the
    following definition:
| 1 2 3 4 5 | static void foreach_node (ClutterPathNode *path_node, gpointer user_data) { } |
