* clutter_actor_hide_all() on the actor. Defaults to calling
* clutter_actor_hide(). This virtual function is deprecated and it
* should not be overridden.
* @realize: virtual function, used to allocate resources for the actor;
* it should chain up to the parent's implementation. This virtual
* function is deprecated and should not be overridden in newly

* @unrealize: virtual function, used to deallocate resources allocated
* in ::realize; it should chain up to the parent's implementation. This

* actor; it is used by clutter_actor_allocate(); when overriding this
* function without chaining up, clutter_actor_set_allocation() must be
* called and children must be allocated by the implementation, when
* chaining up though, those things will be done by the parent's
* implementation.
* @apply_transform: virtual function, used when applying the transformations
* to an actor before painting it or when transforming coordinates or
* the allocation; if the transformation calculated by this function may
* have changed, the cached transformation must be invalidated by calling
* clutter_actor_invalidate_transform(); it must chain up to the parent's

* @has_overlaps: virtual function for
