Revision 613655

Change the "Use antialiasing" checkbox to tristate, defaulting
to nochange that doesn't write out any fontconfig changes. Some distros
have rather complex setup for fonts and changing anything in the fonts
module overrode those settings. Since the default doesn't write out
any changes, already made user changes are also preserved.
BTW, Helio, you have not forwardported any of those "Setting module to use system defaults"
commits, have you?
