15//! Dummy scene node for adding additional transformations to the scene graph.
16/** This scene node does not render itself, and does not respond to set/getPosition,
17set/getRotation and set/getScale. Its just a simple scene node that takes a
18matrix as relative transformation, making it possible to insert any transformation
19anywhere into the scene graph.
20This scene node is for example used by the IAnimatedMeshSceneNode for emulating
21joint scene nodes when playing skeletal animations.
