* and a default easing mode of %CLUTTER_EASE_OUT_CUBIC, unless you call
* clutter_actor_set_easing_mode() and clutter_actor_set_easing_duration()
* after changing the easing state of the actor.</para>
* <para>It is important to note that if you modify the state on an
* animatable property while a transition is in flight, the transition's
* final value will be updated, as well as its duration and progress
* mode by using the current easing state; for instance, in the following
* example:</para>
* <informalexample><programlisting>
* clutter_actor_save_easing_state (actor);
* clutter_actor_set_x (actor, 200);
* clutter_actor_restore_easing_state (actor);
*
* clutter_actor_save_easing_state (actor);
* clutter_actor_set_x (actor, 100);
* clutter_actor_restore_easing_state (actor);
* </programlisting></informalexample>
* <para>the first call to clutter_actor_set_x() will begin a transition
* of the #ClutterActor:x property to the value of 200; the second call
* to clutter_actor_set_x() will change the transition's final value to
* 100.</para>
* <para>It is possible to retrieve the #ClutterTransition used by the
* animatable properties by using clutter_actor_get_transition() and using
* the property name as the transition name.</para>
