bug#578: 23.0.60; Cocoa, Font dialog doesn't set font size

[Benjamin Riefenstahl]

In GNU Emacs 23.0.60.1 (powerpc-apple-darwin8.11.0, *Step 9.0)
 of 2008-07-19 on sueton.benny.turtle-trading.net
configured using `configure  '--with-ns' '--with-png' '--with-gif' 
'--with-jpeg' '--with-tiff''

When setting the font via the font dialog either from the menu item
"Set Default Font..." or from the preferenc es dialog, only the font
family, but not the font size is actually configured.

The attached patch fixes the problem by passing XLFDs around instead
of Mac font names and eliminating the "FontSize" parameter from the
defaults database.


2008-07-19  Benjamin Riefenstahl  <b.riefenstahl@turtle-trading.net>

        * lisp/term/ns-win.el (ns-save-preferences): Do not save defaults
         parameter "FontSize".
         (ns-respond-to-change-font): Construct an XLFD to pass to
         set-frame-font.
        * src/nsfns.m (Fns_create_frame): Do not use defaults parameter
        "FontSize".
