## Iterating over a ClutterPath

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:

      static void
      foreach_node (ClutterPathNode *path_node,
                    gpointer         user_data)
      {
      }
