This is new API I added to support the work I have been doing in VTK's 2D API. 
There is no reason that further overloads could not be added to vtkPolyData to 
handle this type, but I have not had time to do that yet.

Currently vtkPoints2D is used within the 2D API I have been working on. I can 
update the API docs to reflect this, but in the future it could certainly be 
more widely used (and probably should be).
