// .NAME vtkPolyDataToImageStencil - use polydata to mask an image
// .SECTION Description
// The vtkPolyDataToImageStencil class will convert polydata into
// an image stencil.  The polydata can either be a closed surface
// mesh or a series of polyline contours (one contour per slice).
// .SECTION Caveats
// If contours are provided, the contours must be aligned with the
// Z planes.  Other contour orientations are not supported.
// .SECTION See Also
// vtkImageStencil vtkImageAccumulate vtkImageBlend vtkImageReslice
