// OK, so the listener moved. Since our sound soft volumes are all based on
// the listener's position, we have to update all sounds with soft volumes
// now. This involves some steps:
// - Determining what volumes the listener has moved out of
// - Determining what volumes the listener has changed position in
// - Determining what volumes the listener has entered
// - Updating the levels of all sounds associated with all of the above
// volumes
// The first two tests are easy, since we'll have kept track of what volumes
// the listener was in last time. The last part is the tricky one and the
// one that will kill us in performance if we're not careful. However, we
// can first check the bounding box of the sounds in question, since outside
// of them the soft volume won't have any effect. The last part is simply a
// matter of querying the sound volumes based on the listener's position and
// setting the soft volume attenuation on the sound to that level.
//
// Note: for each sound that is still in range, we call CalcSoftVolume() and
// use the resulting value to rank each sound. Then, we take the top n sounds
// and disable the rest. We *could* rank by distance to listener, which would
// be far faster; however, we could have a sound (or background music) that
// is technically closest to the listener but completely faded by a soft volume,
// thus needlessly cutting off another sound that might be more important.
// This way is slower, but better quality.
// Also note: to differentiate between two sounds in the same soft volume at
// full strength, we divide the soft volume ranks by the distSquared, thus
