What would this lisp hook do, and where?

Merely controlling the order of window display is no great feat.
Determining window starts for these Follow Mode windows is the difficult
bit.  Currently Follow Mode fights with the display engine to get what
it needs, often resulting in delays of several tenths of a second in the
subsequent redisplay operations after the first one.
