toggle-frame-maximized

[Sam Steingold]

A de-facto standard keybinding is f11: maximize/full screen the window.
(chrome, gnome-terminal, freeciv - all comply).

Here is an implementation for emacs:

--8<---------------cut here---------------start------------->8---
(defcustom frame-maximization-mode 'maximized
  "The maximization style of \\[toggle-frame-maximized]."
  :version "24.4"
  :type '(choice
          (const :tab "Respect window manager screen decorations." maximized)
          (const :tab "Ignore window manager screen decorations." fullscreen))
  :group 'frames)

(defun toggle-frame-maximized ()
  "Maximize/un-maximize Emacs frame according to `frame-maximization-mode'."
  (interactive)
  (modify-frame-parameters
   nil `((fullscreen . ,(if (frame-parameter nil 'fullscreen)
                            nil frame-maximization-mode)))))

(define-key global-map [f11] 'toggle-frame-maximized)
--8<---------------cut here---------------end--------------->8---

I think this should go into frame.el.
Objections?
