Cubic mapping is supposed to be good from the UI slider to the actual linear 
attenuation factor. We use it to replace the crappy old linear mapping.

Of course, if the mapping from ISimpleAudioVolume to actual attenuation is not 
linear, then by composition, cubic scale will not do what was intended, and 
will probably not be nice. If that is the case, then pristine 
ISimpleAudioVolume is probably better.
