/**************************************************************************
 * NifTK Note: This is take from ITK 3.16.0 (hence the name).
 * It is a cut and paste with a name change, as the spec changed between
 * ITK version 3.16.0 and 3.20.0. The version in 3.20.0 additionally checks
 * fields like the vox_offset, which at the DRC are incorrectly set. This
 * version taken from ITK version 3.16.0, and the derived subclass called
 * itkDRCAnalyzeImageIO3160.h were are used, even though it is older.
