If we bake it into the redisplay code, we can indeed do it "on the fly",
but if we want this feature to be implemented in Elisp it seems a lot
more tricky to avoid the 2 passes.

Right.

Right. And they're different for different windows displaying the
same buffer.

Well, to the extent that point probably changes when the window is
scrolled, yes. Otherwise not necessarily.
