  //  Class: avtImageFileWriter
  //
  //  Purpose:
  //      A type of image sink that writes the image to a specified file format.
  //
  //  Programmer: Hank Childs
  //  Creation:   February 12, 2001
  //
  //  Modifications:
  //
  //    Brad Whitlock, Tue Feb 13 14:40:23 PST 2001
  //    I added a couple member functions and some static data members.
  //
  //    Hank Chlids, Mon Jun  4 09:06:58 PDT 2001
  //    Inherited from avtTerminatingImageSink.
  //
  //    Brad Whitlock, Wed Jan 23 14:57:52 PST 2002
  //    I added a couple new arguments to the Write method that allow some
  //    format specific options to be passed in.
  //
  //    Brad Whitlock, Wed Feb 20 17:17:42 PST 2002
  //    I added a new Write method that takes a writer.
  //
  //    Hank Childs, Fri May 24 10:51:28 PDT 2002
  //    Stop passing images as arguments, since SetInput is the approved route.
  //
  //    Kathleen Bonnell, Thu Nov  6 07:44:38 PST 2003
  //    Added compression arg to Write method.
  //
  //    Hank Childs, Thu Feb  5 17:11:06 PST 2004
  //    Moved inlined destructor definition to .C file because certain compilers 
  //    have problems with them.
  //
  //    Brad Whitlock, Mon Mar 6 17:35:28 PST 2006
  //    I made it reset nFilesWritten if the nase changes.
