* 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.

*
* - 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

*
* Limitation:
*
* - The animated properties must be compatible among the
* all objects in the group.
*
* - A single property can either be controlled through a
