  8268. * A group of objects that receives a shared animation state.
  8269. *
  8270. * Usage:
  8271. *
  8272. * - Add objects you would otherwise pass as 'root' to the
  8273. * constructor or the .clipAction method of AnimationMixer.
  8274. *
  8275. * - Instead pass this object as 'root'.
  8276. *
  8277. * - You can also add and remove objects later when the mixer
  8278. * is running.
  8279. *
  8280. * Note:
  8281. *
  8282. * Objects of this class appear as one object to the mixer,
  8283. * so cache control of the individual objects must be done
  8284. * on the group.
  8285. *
  8286. * Limitation:
  8287. *
  8288. * - The animated properties must be compatible among the
  8289. * all objects in the group.
  8290. *
  8291. * - A single property can either be controlled through a
  8292. * target group or directly, but not both.
