How to determine the menu-bar dimensions: width and height, say in pixels?
In some cases, such as Windows, the menu-bar characters seem to be set by
the window manager; in other cases they are governed by the Emacs `menu'
face or the .Xdefaults file. Anyone have an idea how to calculate the
overall dimensions of the menu-bar? (Similarly for the tool-bar.)

I messed with this for a very long time. I don't know why. I don't
actually care. I guess I thought it should be easy and got caught up
in it after a while.
This works for the toolbar provided there is only 1 window in the
frame.
(progn (tool-bar-mode 0)
(sit-for 0)
(let ((fph (frame-pixel-height))
(wh (window-height)))
(tool-bar-mode 1)
(sit-for 0)
(+ (* (- wh (window-height))
(frame-char-height))
(- (frame-pixel-height) fph))))
But there seems to be a bug (cvs) that prevents similar code from
working for the menu bar. Apparently (frame-char-height) doesn't
count the menu bar and for that matter neither does (frame-height).
I'll try to write it up in the morning. If you're working on a non MS
Windows system the bug may not apply and the above may work for
toggling menu-bar-mode too.
