bug#8109: 23.2; Fontconfig issues

[Eli Barzilay]

First, I've seen somewhere (on the popular emacs wiki maybe) a hint on
disabling antialiasing by using "Fontname-12:antialias=none".  After a
bunch of failures, I finally got it to work with a 0 instead:
"Fontname-12:antialias=0".  It's probably a good idea to include this
in the info file, since it's pretty hard to deal with.

But I have a real problem with the antialiasing now.  If I set the
font on startup to a non-antialiased font, it will stay this way.  For
example, if I use `set-frame-font' with "Fontname-12" after I used
the "...:antialias=none" initially, then it doesn't change the font
back to a smooth one.

And the reason I want this: I want to run with no antialiasing in a
vnc session in my office to make remote work faster, but I want to be
able to open a new frame locally on :0, *with* smoothing, when I'm in
the office.  With Emacs v23.1, I did that by using a different
xdefaults for the two displays, but since 23.2 it seems like there is
no effect in what emacs actually uses.
