//  Class: avtImage
//
//  Purpose:
//      This is another data object that avt pipelines can handle.  It is an
//      image (vtkImageData).  Further modifications may need to be made to
//      allow for multiple images as in image compositing or tiling.
//
//  Programmer: Hank Childs
//  Creation:   November 21, 2000
//
//  Modifications:
//
//    Hank Childs, Wed Nov 21 12:08:42 PST 2001
//    Re-define DerivedCopy.
//
//    Hank Childs, Thu Feb  5 17:11:06 PST 2004
//    Moved inlined constructor and destructor definitions to .C files
//    because certain compilers have problems with them.
//
//    Mark C. Miller, Wed Feb  4 19:47:30 PST 2004
//    Added Instance, needed by avtDataObject->Clone
//
//    Mark C. Miller, Wed Mar 31 21:10:56 PST 2004
//    Added GetSize method
//
//    Burlen Loring, Wed Aug 26 09:09:11 PDT 2015
//    Make SetImage public
//
//    Burlen Loring, Sun Sep  6 14:58:03 PDT 2015
//    Changed the return type of GetNumberOfCells to long long
//
