I think we have to distinguish between a redisplay that does a "redraw" and
one that does what the toplevel loop normally.  The "redraw" does call for
a specification of what to redraw, but the normal toplevel redisplay doesn't
(it just looks for things that have changed since the last "redisplay").
For redraw, we already have redraw-display and redraw-frame and
redraw-modeline, so I think we're set.  For forcing the display to be
updated OTOH only sit-for is available and it's not reliable.
