[AS3 only] Constants for defining the direction in which to travel on a MotionPath (like CLOCKWISE, COUNTER_CLOCKWISE, SHORTEST, etc.).
[AS3 only] A LinePath2D defines a path (using as many Points as you want) on which a PathFollower can be placed and animated.
[AS3 only] A MotionPath defines a path along which a PathFollower can travel, making it relatively simple to do things like tween an object in a circular path.
[AS3 only] A PathFollower is used to associate a particular target object (like a MovieClip, Point, Sprite, etc.) with a MotionPath and it offers a tweenable progress property that manages positioning the target on the path accordingly.
[AS3 only] A RectanglePath2D defines a rectangular path on which a PathFollower can be placed, making it simple to tween objects along a rectangle's perimeter.
