// .NAME vtkBSplineTransform - a cubic b-spline deformation transformation
// .SECTION Description
// vtkBSplineTransform computes a cubic b-spline transformation from a
// grid of b-spline coefficients.
// .SECTION Caveats
// The inverse grid transform is calculated using an iterative method,
// and is several times more expensive than the forward transform.
// .SECTION see also
// vtkGeneralTransform vtkTransformToGrid vtkImageBSplineCoefficients
