AnimationMixer

Player for animations on a particular object in the scene.
This class manages animation playback for a specific object, providing methods to control animation timing, playback speed, and action management. When multiple objects are animated independently, one AnimationMixer may be used for each object.

• Time scaling for playback speed
• AnimationAction management
• Memory resource management
• Get actions for animation clips
• Update mixer in render loop
