experiment: pan editor on a larger surface

This works but has a drawback: since we just adjust Editor.top, we render everything from Editor.top to bottom of screen. If we pan a long distance, Editor.top can become a large negative number and the editor will spend more and more time rendering things outside screen.

I suppose we'll find out what these no-op draws cost us.
