Detailed Description
A DisplayObject that tweens between two shapes.
A MorphShape has no properties of its own, but its inherited properties may be read in AS3 using a reference to the object created with getChildAt(). Morphing is controlled using a SWF::PlaceObject2 tag with a ratio flag. The most common and efficient way is to combine this with a move flag, so that this object is moved to the position specified by the ratio. However, it is also possible to remove and replace, in which case a new MorphShape is created. The starting position is not necessarily identical with shape1, though in practice it often is.
