- * A group of objects that receives a shared animation state.

- *
- * - Instead pass this object as 'root'.
- *
- * - You can also add and remove objects later when the mixer

- *
- * Note:
- *
- * Objects of this class appear as one object to the mixer,
- * so cache control of the individual objects must be done
- * on the group.
- *
- * Limitation:
- *
- * - The animated properties must be compatible among the
- * all objects in the group.
- *
- * - A single property can either be controlled through a
- * target group or directly, but not both.
