This is wrong. You want the _points_, not the vertices. Those are going down 
the loo here:

You'd need a sdt::vector<Point>, then push back the _points_ on that vector:

Also, beware you may do this in a point-by-point fashion. You may insert a 
new 
point, then delete the old one (or perhaps, delete then insert). This is 
tricky, but there is a move() function to do this, which I am currently 
trying 
(I think it is not documented, but it's right there in the .h source).

Best,

Daniel
