// .NAME vtkMNITransformWriter - A writer for MNI transformation files.
// .SECTION Description
// The MNI .xfm file format is used to store geometrical
// transformations.  Three kinds of transformations are supported by
// the file format: affine, thin-plate spline, and grid transformations.
// This file format was developed at the McConnell Brain Imaging Centre
// at the Montreal Neurological Institute and is used by their software.
// .SECTION See Also
// vtkMINCImageWriter vtkMNITransformReader
// .SECTION Thanks
// Thanks to David Gobbi for writing this class and Atamai Inc. for
// contributing it to VTK.
