Thank you, Eli, for the detailed explanation in your most recent e-mail -- greatly appreciated.

Assuming the correct values are available through Lisp when using the `post-redisplay-hook` and assuming that there is no buffer modification (attached to that new hook) that moves point or changes font sizes, I am unaware of any other prospective problem areas.  The minor-mode in my previous e-mail should be sufficient for us to visually see how it works with some basic things like scroll-up/down, beginning/end-of-buffer, next/previous-line when at the window edges.
