interesting concept, embedding the clickable area in the TIFF needs
5 (private) tags per area: {x, y, width, height, URL} or at
least 3 { x, y, URL} using a closest point algorithm.
Drawback: manipulating the image could corrupt the integrity and
validity of the area params if they are preserved at all.
(integrity tag needed)
Still it offers interesting possibilities ...
