* @class vtkImageToStructuredPoints
* @brief Attaches image pipeline to VTK.
*
* vtkImageToStructuredPoints changes an image cache format to
* a structured points dataset. It takes an Input plus an optional
* VectorInput. The VectorInput converts the RGB scalar components
* of the VectorInput to vector pointdata attributes. This filter
* will try to reference count the data but in some cases it must
* make a copy.
