*
* - Actors emit pointer events if set reactive (#clutter_actor_set_reactive)
* - Keyboard events are emitted if actor has focus (#clutter_stage_set_focus)
* - Motion events (motion, enter, leave) are only emitted per actor if

* then only the stage emits events.
* - One emitted an event emission has two phases - capture and bubble.
