|Subject:||bug#16129: 24.3.50; Emacs slow with follow-mode when buffer ends before last window|

> Basically, it is supposed to do whatever Follow mode does todayThat is not specific enough, especially if you take into consideration
that I have only a vague idea about what Follow mode does. Moreover,
I'm not sure we should ask the display engine do everything it does.
For example, selecting the next/previous window when point moves off
the limits of the current window seems to be something that is easy to
do in Lisp.
So please do try to come up with a list of requirements that should be
moved to the display engine. I guess setting the window start point
when scrolling would be one; what else?
