I see.  See my reply to Eli too, however.  In the example I gave using
an Emacs 25 build (not very recent) it returned good results, but
`posn-at-point' seemed to be off.

Anyway, I'm glad to see `window-absolute-pixel-position' and `frame-geometry'.

It would still be useful, I think, to have a function that returns
directly the screen-relative pixel coordinates (i.e., even though
that can be got using `window-absolute-pixel-position' and
`frame-geometry'.)
