 * in tiff.h.  Note also that the varargs interface used
 * to pass tag types and values uses the types defined in
 * 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 signed and not unsigned because some functions
 *     return -1.
 * NB: toff_t is not off_t for many reasons; TIFFs max out at
 *     32-bit file offsets, and BigTIFF maxes out at 64-bit
 *     offsets being the most important, and to ensure use of
 *     a consistently unsigned type across architectures.
 *     Prior to libtiff 4.0, this was an unsigned 32 bit type.
