fontconfig update uglifies fonts

[Russell L. Carter]

Hi,

On 10/stable amd64, the recent fontconfig update makes the fonts used
in thunderbird, firefox, (u)xterm, and emacs quite a bit uglier.  The
font strokes seem to be thicker and fuzzier.  Emacs I fixed by
reinstalling bitstream-vera, but (u)xterm use that and they're still
broken.  I ran fc-cache -f, but no change.  I turned off antialiasing
via /usr/local/etc/fonts/local.conf and that made the strokes nice and
thin but overall even uglier.

Any ideas/pointers on how to fix this?

Thanks,
Russell
