bug#7398: 23.2.90; Missing descenders in menu and toolbar tooltips

I guess it's just that emacs refuses to draw outside of the
buffer-window.  A buffer-window in emacs is not necessarily as
big as the available space, in particular not when that space is
less than the next multiple of the size of the default-font size.
