// .NAME vtkImageStencilAlgorithm - producer of vtkImageStencilData
// .SECTION Description
// vtkImageStencilAlgorithm is a superclass for filters that generate
// the special vtkImageStencilData type.  This data type is a special
// representation of a binary image that can be used as a mask by
// several imaging filters.
