 *
 * Lossless JPEG compression and decompression algorithms.
 *
 * ---------------------------------------------------------------
 *
 * It is based on the program originally named ljpgtopnm and pnmtoljpg.
 * Major portions taken from the Independetn JPEG Group' software, and
 * from the Cornell lossless JPEG code (the original copyright notices
 * for those packages appears below).
 *
 * ---------------------------------------------------------------
 *
 * This is the main routine for the lossless JPEG decoder.  Large
 * parts are stolen from the IJG code
