Nevertheless, computer, and not human, being the 'primary reader', I can't help
wondering what is wrong with the plain old WORD value? What is wrong with the
old tags? I can only see what is right: almost 15 years of experience and
evolution, a webfull of documentation, and an existing library with very few
misunderstandings.

Why is everybody so keen in discussing changes that are at best not needed and
rather auxilliary to the issue? This discussion started of with the goal
extending the size limits of TIFF. A plain obvious clean tranformation from
32bit count/offset values to 64bit would do that, so we may want to discuss that
instead. Another real issue is signature value, new header. A big issue may be
the size limits to individual strips/tiles, like can we keep old compression
scemes unchanged or not? I'm not seeing this being discussed at all.

From a LibTiff point of view: I recently noticed someone asking whether the
individual codecs in LibTiff can be used all by themselves, with another
encapsulator. Is there any defenite answer/progress in this field? It would seem
like this may be a first basis for extending LibTiff in whatever new 64bit
direction. I am also personally interested in this, for use in a 32bit as well
as 64bit offset based ObjectPascal encapsulator.
