If IsClosed, just return true. Otherwise, decide if curve can be closed as
follows: Linear curves polylinear curves with 2 segments, Nurbs with 3 or less
control points cannot be made closed. Also, if tolerance > 0 and the gap between
start and end is larger than tolerance, curve cannot be made closed.
Adjust the curve's endpoint to match its start point.
