I think the following is a bug:

emacs -q

(progn
  (setq aaa (make-frame))
  (set-mouse-position aaa 1 1)
  (sit-for 3)
  (iconify-frame aaa)
  (set-mouse-position aaa 1 1))

and evaluate.

You will see that the mouse pointer will remain where it was.
Moreover, if later you eval, say,

(set-mouse-position aaa 4 4)


Then the pointer will move to the pos 4,4 relative to the place the frame
in aaa would have been, if we deiconify it.

In other words, set-mouse-position remembers where the frame was and puts
cursor there. Since this place may now be occupied by some other place (or
it may be empty), such behavior doesn't make much sense.

The expected behavior is to move pointer to where the icon is.  (I think,
if frame is iconified, pointer should move it to the center of the icon and
ignore the coordinates given in set-mouse-position.)
