+ *
+ * - 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,

+ *
+ * Limitation:
+ *
+ * - The animated properties must be compatible among the

+ *
+ * - A single property can either be controlled through a
+ * target group or directly, but not both.
