#### Interfaces

UndoHandler | This interface is implemented by objects (e.g. the annotation context) that aim to register actions that may be undone. Such actions must be registered into the undo context so as they are added to the undo stack with `pps_undo_context_add_action`. Then, when an action must be undone (e.g. the user pressed Ctrl+Z), the `pps_undo_handler_undo` interface method is called on the object. An action is represented by an arbitrary pointer. The object must free such pointers when the `pps_undo_handler_free_action` interface method is called.
