 * tiff.h directly.
 *
 * NB: ttag_t is unsigned int and not unsigned short because
 *     ANSI C requires that the type before the ellipsis be a
 *     promoted type (i.e. one of int, unsigned int, pointer,
 *     or double) and because we defined pseudo-tags that are
 *     outside the range of legal Aldus-assigned tags.
 * NB: tsize_t is int32 and not uint32 because some functions
 *     return -1.
 * NB: toff_t is not off_t for many reasons; TIFFs max out at
 *     32-bit file offsets being the most important, and to ensure
 *     that it is unsigned, rather than signed.
