 * @class   vtkSMPTransform
 * @brief   Transform that uses the SMP framework
 *
 * 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.
