Coming back ... - the code below seems to do what I want. Comments,
suggestions? Can someone please test on X? Mac?

Changes to tooltip.el:

(defvar tooltip-mouse-pixel-position nil)

(defun tooltip-timeout (object)
  "Function called when timer with id tooltip-timeout-id fires."
  (if (and
       (equal (nth 0 tooltip-mouse-pixel-position) (nth 0
(mouse-pixel-position)))
       (> 10 (abs (- (nth 1 tooltip-mouse-pixel-position) (nth 1
(mouse-pixel-position)))))
       (> 10 (abs (- (nthcdr 2 tooltip-mouse-pixel-position)
       (nthcdr 2 (mouse-pixel-position))))))
      (progn
 (run-hook-with-args-until-success 'tooltip-hook
       tooltip-last-mouse-motion-event))
    ;;(message "%s ### %s" tooltip-mouse-pixel-position
(mouse-pixel-position))
    ))

(defun tooltip-start-delayed-tip ()
  "Add a one-shot timeout to call function tooltip-timeout."
  (setq tooltip-mouse-pixel-position (mouse-pixel-position))
  (setq tooltip-timeout-id
 (add-timeout (tooltip-delay) 'tooltip-timeout nil)))
