        )
Adjust volume region to include a zone.  If current volume region is
 much bigger than that needed for the zone, then shrink it.  The purpose
 of this resizing is to keep the region small so that recontouring is fast,
 but not resize on every new zone radius.  Resizing on every new zone
 radius requires recontouring and redisplaying the volume histogram which
 slows down zone radius updates.
