* 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 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, and BigTIFF maxes out at 64-bit

* offsets being the most important, and to ensure use of

* a consistently unsigned type across architectures.
