Updating the tour for Xft

[David House]

Hi all,

Now we have nice anti-aliased fonts with 23.1, can we update the tour
(http://www.gnu.org/software/emacs/tour/) so that it shows off this
nice new visual feature?

The tour is a great way of showing off Emacs' features and visual
features have a massive impact, so this seems like a logical thing to
do.
