[vtkusers] more local control for thin plate transform

[Qing Hu]

ok, after a little longer consideration, I think you can do this by the
following way.


(1) add the scalar attribute to each points of the mesh. for example, 
"-1" to the points which should be deformed, "1" to the points which
will not changed. 

(2) using the "vtkThinPlateSplineTransform" to deform your mesh.

(3) Combine the transformed mesh with the original mesh, just a little
programming need to do to merge these two model according their points'
scalar value.

I hope I have make my words clear. good luck :)
