Returns the Source (or ActionSource) object which is instantiated by this clip. For example, if the clip is an instance of an action source (ie., an animation or shape animation source item), then the ActionSource object is returned. If the clip is an instance of an audio or image source, the Source object is returned.

Note: The source returned here stores animation, audio, or image data. This is not the same as the animation data that is driving the parameter, such as an FCurve or a ShapeKey. To access those DataSource elements, use the MappedItem.Source2 property on the Clip.MappedItems collection items.
