/**
* @class vtkTransformPolyDataFilter
* @brief transform points and associated normals and vectors for polygonal dataset
*
* vtkTransformPolyDataFilter is a filter to transform point
* coordinates and associated point and cell normals and
* vectors. Other point and cell data is passed through the filter
* unchanged. This filter is specialized for polygonal data. See
* vtkTransformFilter for more general data.
*
* 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
* vtkTransformPolyDataFilter actually modifies point coordinates in the
* visualization pipeline. This is necessary for some objects
* (e.g., vtkProbeFilter) that require point coordinates as input.
