[vtkusers] Improving 3D surface

[Bill Lorensen]

1) You could use vtkImageMagnify on the scalars. Make sure you turn interpolation on. You apply this filter to your scalars.

2) You could use vtkLoopSubidivisionFilter to generate a subdivision surface. This filter requires triangles. You would apply this to either the output of the PlaneSource of the WarpScalar.
