The library is designed to hide as much of the details of TIFF from
applications as
possible.  In particular, TIFF directories are read in their entirety
into an internal format.  Only the tags known by the library are
available to a user and certain tag data may be maintained that a user
does not care about (e.g. transfer function tables).
