Subject: puzzles: Follow cursor in zoom mode and general code cleanup.

Frontends now have a way to retrieve the backend cursor position with some
changes I've submitted upstream. With this information, we can now follow
the cursor around in "interaction mode" while zoomed in, eliminating (most)
need for mode switching.

Also does some cleanup of the frontend code.
