59 * ANSI C requires that the type before the ellipsis be a
60 * promoted type (i.e. one of int, unsigned int, pointer,
61 * or double) and because we defined pseudo-tags that are
62 * outside the range of legal Aldus-assigned tags.
63 * NB: tsize_t is int32 and not uint32 because some functions
64 * return -1.
65 * NB: toff_t is not off_t for many reasons; TIFFs max out at
66 * 32-bit file offsets being the most important
