/**
 * SECTION:clutter-action
 * @Title: ClutterAction
 * @Short_Description: Abstract class for event-related logic
 * @See_Also: #ClutterConstraint
 *
 * #ClutterAction is an abstract base class for event-related actions that
 * modify the user interaction of a #ClutterActor, just like
 * #ClutterConstraint is an abstract class for modifiers of an actor's
 * position or size.
 *
 * Implementations of #ClutterAction are associated to an actor and can
 * provide behavioral changes when dealing with user input - for instance
 * drag and drop capabilities, or scrolling, or panning - by using the
 * various event-related signals provided by #ClutterActor itself.
 *
 * #ClutterAction is available since Clutter 1.4
