I hope you will consider that the simplest thing to do is to follow the
specification and try to do things in such a way that in the long run
there should be no need for a prompt or a preference?  I do realise
thatrotating the view without rotating the image itself is making things
complicated but perhaps it would be possible to have the importer take
care of the rotation and the exporter rotating back as needed, and still
preserving all EXIF metadata?
