Folks,

I'm a bit late on this discussion, but I have only one thought: if the
one can construct the file with TileWidth/Height = 1, then we must be
able to store as many tile offsets/counts as pixels in the image. If the
TileOffsets/Counts will be limited by the 32-bit value then we should
add special clause to the specification discussing the problems when the
Strip/Tile things exceed the 64 bit.

That is why the solution with 64 bit tag counts looks simpler for me.
