// .NAME vtkImageEllipsoidSource - Create a binary image of an ellipsoid.
// .SECTION Description
// vtkImageEllipsoidSource creates a binary image of a ellipsoid.  It was created
// as an example of a simple source, and to test the mask filter.
// It is also used internally in vtkImageDilateErode3D.
