Thanks.  It's not clear to me how `pos-visible-in-window-p'
would enter the picture (except to confirm that a position
is visible before asking for its pixel coordinates, and for
`point' that is always the case), but I guess I can see how
`window-absolute-body-pixel-edges' might help.

Unfortunately for me, I cannot use anything from Emacs 25,
as it is hopelessly broken, so far, at least in my context.
At this point I can only hope that someone else eventually
reports problems similar to those I've reported (e.g. crashes)
and has better luck than I in tracking down the causes and
getting them fixed.

But I continue to follow Emacs development, and I continue 
to try new builds of 25, just in case.  (I make no claim that
my case is typical, obviously.)
