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.
