The constant vertex_point is a property tag which refers to the geometric embedding property of a vertex of a HalfedgeGraph.
A vertex_point is an interior property, that is, a property map for a vertex_point can be extracted from any model of a HalfedgeGraph using the Bgl PropertyGraph interface:
boost::get(vertex_point,graph)
A point of a vertex can be directly accessed via:
boost::get(vertex_point,graph,vertex)
boost::put(vertex_point,graph,vertex,newpoint)
