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.
