// at which volume is silent) for things like culling, and volume tweaking. NOTE - after the
// last point on the volume curve, XACT no longer attenuates the volume, so it's possible to
// have a sound heard infinitely far away. This deals with that quite happily - the maximum
// distance is where the volume is silent, not merely the last point on the graph.
