... for what its worth. I also wrote a tooltip-at-point-elisp package so that you can run C-? and lookup a symbol at point.
I can post both of these here.
It would be NICE to have an official way to do this......

(point-to-coord (point))
(posn-at-point (point))
(set-window-margins (selected-window) 20 0)
(point-to-coord (point))
(posn-at-point (point))
I get the same result before and after set-window-margins.
