What I wonder is if xemacs actually supports it _correctly_, or whether they
just use a sort of `mostly works' heuristic like I mentioned before.  I think
that emacs' display model makes it impossible to actually do it right without
rendering the entire document before the current window to calculate the
correct vertical offset (and they certainly aren't going to do that).
