You could do that, but the problem grows expoentially when you take
into account fonts (different font sizes, different character size per
language, etc). Then you have to worry about images.  Since each
individual image's height/width isn't stored anywhere in the .pdb we
have to open up each unique record, size it, and find out how it
relates to the text to push the overall size of the page down.

I havn't used isilo in a long time, but I believe that they support a
much smaller subset of fonts/languages than we do. I'm not sure on how
they handle images exactly.

Since all of this is required for the accuracy of the scrollbar and
the percentage pulldown, sacrifices might be acceptable.

Maybe the viewer can be setup to render the whole page (or pages)
during the palm's idle loop (in other words, while the user is reading
the current page).

There are multiple ways to solve this problem. The trouble is finding
the time -- or someone to volunteer :) -- to do it.
