A node to be used for advanced animation transitions in an $(D AnimationPlayer).

Note: When linked with an $(D AnimationPlayer), several properties and methods of the corresponding $(D AnimationPlayer) will not function as expected. Playback and transitions should be handled using only the $(D AnimationTree) and its constituent $(D AnimationNode)(s). The $(D AnimationPlayer) node should be used solely for adding, deleting, and editing animations.
