*
* 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.
