Point_2< Kernel > operator- (const Point_2< Kernel > &p, const Vector_2< Kernel > &v)
 returns the point obtained by translating p by the vector -v.
 
Point_3< Kernel > operator- (const Point_3< Kernel > &p, const Vector_3< Kernel > &v)
 returns the point obtained by translating p by the vector -v.
