/// Places each external constraint shape at the point corresponding to the average of all of its referenced shapes.
/// Frequency constraints are handled differently, since they apply to only one fact type (but 1 or more roles in that
/// fact type) at any time.
/// </summary>
/// <param name="minimumPoint">The minimum location for new element placement</param>
