Stupid question --- is there a way to force the right thing to happen
from emacs-lisp?  My biggest gripe is that I couldn't figure out a way
to make the right thing happem from my .emacs.el file, despite a lot
of time spent trying to find the right interfaces via M-x apropos.  So
at the moment, I'm firing up emacs, and then having to use
Options->Set Default Font from the menu bar to change to a small font
size.  (And I'm an old-school emacs person who normally would run with
the menu bar and tool bar disabled.  :-)

I suspect the correct default though should be to give the xft font
backend a higher priority; especially at the moment, where many people
are using emacs-snapshot *because* of the nicer font display.

Thanks, regards,
