Right.  Which is why lbshell.js uses a known "image" for the background so it
can restore arbitrary rectangles of the screen.  I've actually looked into
having Synchronet track outgoing ANSI so it *could* restore arbitrary parts of
the screen, but decided I didn't want to bother since I personally wouldn't use
that often enough.
