// Class: avtImageFileFormat
//
// Purpose:
// Reads in Image files as a plugin to VisIt.
//
// Programmer: Chris Wojtan
// Creation: Thu Jun 3 09:50:31 PDT 2004
//
// Modifications:
// Mark C. Miller, Thu Nov 4 17:00:40 PST 2004
// Added support for data selections. Eliminated xdim/ydim data members
// since they are known from vtkImageData object
//
// Mark C. Miller, Tue Nov 9 13:41:33 PST 2004
// Removed unnused pointvarnames, pointvars. Added fext and CanCacheVariable
//
// Hank Childs, Fri Mar 18 11:41:04 PST 2005
// Added support for image volumes.
//
// Mark C. Miller, Tue May 17 18:48:38 PDT 2005
// Deleted a bunch of commented-out code that was hold-over from the
// plugin generation processes.
