/**************************************************************************
 * NifTK Note: This is take from ITK 3.20.1 (hence the name), which was
 * the version of ITK used within NifTK at the time of writing. The
 * version 3.20.1 actually signified a patched version of ITK, and
 * the patched tar file and patch can be seen in:
 *   NifTK/CMake/ExternalProjects/ITK.cmake and
 *   NifTK/CMake/ExternalProjects/PatchITK-3.20.cmake
 * However, none of this patching affects the Nifti reader, so the base
 * version of the Nifti reader used for this class is the same as in 3.20.0.
 *
 * The changes supplied here are to include the sform in the transformation.
