 * Animation component for A-Frame using anime.js.

 * boolean * flag * `isAnimationPlaying`.
 *
 * anime.js animation config for tweenining Javascript objects and values works as:
 *
 *  config = {
 *    targets: {foo: 0.0, bar: '#000'},
 *    foo: 1.0,
 *    bar: '#FFF'
 *  }
 *
 * The above will tween each property in `targets`. The `to` values are set in the root of
 * the config.
 *
 * @member {object} animation - anime.js instance.
 * @member {boolean} animationIsPlaying - Control if animation is playing.

 * This class generates a Prefiltered, Mipmapped Radiance Environment Map

 * blur to be quickly accessed based on material roughness. It is packed into a
 * special CubeUV format that allows us to perform custom interpolation so that
 * we can support nonlinear formats such as RGBE. Unlike a traditional mipmap
 * chain, it only goes down to the LOD_MIN level (above), and then creates extra
 * even more filtered 'mips' at the same LOD_MIN resolution, associated with
 * higher roughness levels. In this way we maintain resolution to smoothly
 * interpolate diffuse lighting while limiting sampling computation.

 *
 * A group of objects that receives a shared animation state.
 *
 * Usage:
 *
 *  - Add objects you would otherwise pass as 'root' to the
 *    constructor or the .clipAction method of AnimationMixer.
 *
 *  - Instead pass this object as 'root'.
 *
 *  - You can also add and remove objects later when the mixer
 *    is running.
 *
 * Note:
 *
 *    Objects of this class appear as one object to the mixer,
 *    so cache control of the individual objects must be done
 *    on the group.
 *
 * Limitation:
 *
 *  - The animated properties must be compatible among the
 *    all objects in the group.
 *
 *  - A single property can either be controlled through a
 *    target group or directly, but not both.
