 * The following typedefs define the intrinsic size of

 * data types used in the *exported* interfaces.  These

 * definitions depend on the proper definition of types

 * 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 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.

 *     Prior to libtiff 4.0, this was an unsigned 32 bit type.
