Subject: 24.4; toggle-frame-fullscreen does not always toggle back correctly

In Emacs 24.4, if I call toggle-frame-fullscreen twice, it does not
always return the window to its original size and position, in
particular if it was originally semi-maximized in gnome-shell (filling
half the screen, an effect obtained by dragging the window to its left
or right-hand side).

Replacing toggle-frame-fullscreen with this equivalent function that
uses wmctrl makes it work:

(defun toggle-frame-fullscreen ()
  "Toggle full-screen in X11."
  (interactive)
  (call-process "/usr/bin/wmctrl" nil 0 nil
                "-i" "-r" (frame-parameter nil 'outer-window-id) "-btoggle,fullscreen"))
