Hello.

While trying to reproduce a reported problem with x-popup-menu (that problem 
seems to be gone), I saw that x-popup-menu doesn't put the menu in the correct 
position if the (x y) variant is used, like this:

(x-popup-menu
  (list '(1 1) (selected-window))
  (list "title" (cons "title" '(("ignore" 'ignore)))
        ))

For lucid and motif, this puts the popup menu at a position that would be 
correct if the Emacs edit window is at (0 0) on the root window.  If Emacs is
anywhere else on the root window, this is wrong.

Here is a patch to fix that.  Is it OK to check in?
