[Fontconfig] 'Fixed' font using incorrect font

[James H. Cloos Jr.]

If you want to see what font is being used by fontconfig/xft for any
given name (at least on linux; I don't have access to a bsd box that
runs X to test) try using xfd to show the font; /proc/$pid/maps will
list the font file xfd is using.  lsof -p $pid is an easy way to see
that info.

At 133 dpi, I get this mapping for fixed-9, 10, 11:

fixed-9  == /usr/X11R6/lib/X11/fonts/misc/lt1-16-etl.pcf.gz
fixed-10 == /usr/X11R6/lib/X11/fonts/misc/18x18ko.pcf.gz
fixed-11 == /usr/X11R6/lib/X11/fonts/misc/10x20.pcf.gz

The font you see for fixed-10 is probably one of
the -sony-fixed-medium-r-normal-* fonts.
