 * 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.
