// .NAME vtkImageToStructuredPoints - Attaches image pipeline to VTK.
// .SECTION Description
// 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.
