  26116. * A group of objects that receives a shared animation state.

  26118. * Usage:
  26119. *
  26120. * - Add objects you would otherwise pass as 'root' to the
  26121. * constructor or the .clipAction method of AnimationMixer.
  26122. *
  26123. * - Instead pass this object as 'root'.
  26124. *
  26125. * - You can also add and remove objects later when the mixer
  26126. * is running.
  26127. *
  26128. * Note:
  26129. *
  26130. * Objects of this class appear as one object to the mixer,
  26131. * so cache control of the individual objects must be done
  26132. * on the group.
  26133. *
  26134. * Limitation:
  26135. *
  26136. * - The animated properties must be compatible among the
  26137. * all objects in the group.
  26138. *
  26139. * - A single property can either be controlled through a
  26140. * target group or directly, but not both.
