  23736. * A group of objects that receives a shared animation state.

  23738. * Usage:
  23739. *
  23740. * - Add objects you would otherwise pass as 'root' to the
  23741. * constructor or the .clipAction method of AnimationMixer.
  23742. *
  23743. * - Instead pass this object as 'root'.
  23744. *
  23745. * - You can also add and remove objects later when the mixer
  23746. * is running.
  23747. *
  23748. * Note:
  23749. *
  23750. * Objects of this class appear as one object to the mixer,
  23751. * so cache control of the individual objects must be done
  23752. * on the group.
  23753. *
  23754. * Limitation:
  23755. *
  23756. * - The animated properties must be compatible among the
  23757. * all objects in the group.
  23758. *
  23759. * - A single property can either be controlled through a
  23760. * target group or directly, but not both.
