That would require a `document anchored' background image, which is
hard to do (I explained why in a recent post on this same thread).

Anyway, why not just use a normal image for this, since that's what
most web browsers do for image-maps?

Again this would probably run afoul of the `document anchored' image
restriction, though I admit it would be kinda cool.

Hmm, maybe there's some cheezy heuristic which would get the average
case mostly right.  E.g., just use the line count [is this available to
redisplay if mode-line line-numbers are turned on?] and multiply by the
default face's height.  It'd be wrong for some cases, but it would
usually result in coherent display behavior (the image would scroll in
unison with the text ... most of the time).
