I have been looking into doc-view.  It offers more complete and more
consistent support for scrolling and I am trying to find out how
this can possibly be ported to djvu.el.

On the other hand, I am also wondering whether it could make sense
to add a backend for djvu files to doc-view.  Probably this depends
on what users want to do.  I started djvu.el for editing djvu
documents which is often very different from viewing such files.

Did I see correctly that this code relies on `convert' from
imagemagic for updating the images?

I need some more time to understand better what the code is doing.
