// .NAME vtkSMPTransform - Transform that uses the SMP framework
// .SECTION Description
// Just like its parent, vtkTransform, vtkSMPTransform calculates and
// manages transforms. Its main difference is that it performs various
// transform operations over a set of points in parallel using the SMP
// framework.
// .SECTION See Also
// vtkTransform
