/**
* @class vtkTransformFilter
* @brief transform points and associated normals and vectors
*
* vtkTransformFilter is a filter to transform point coordinates, and
* associated point normals and vectors. Other point data is passed
* through the filter.
*
* An alternative method of transformation is to use vtkActor's methods
* to scale, rotate, and translate objects. The difference between the
* two methods is that vtkActor's transformation simply effects where
* objects are rendered (via the graphics pipeline), whereas
* vtkTransformFilter actually modifies point coordinates in the
* visualization pipeline. This is necessary for some objects
* (e.g., vtkProbeFilter) that require point coordinates as input.
