/** Font configuration scheme
- ./config-compat.patch makes fontconfig try the following root configs, in order:
$FONTCONFIG_FILE, /etc/fonts/${configVersion}/fonts.conf, /etc/fonts/fonts.conf
This is done not to override config of pre-2.11 versions (which just blow up)
and still use *global* font configuration at both NixOS or non-NixOS.
- NixOS creates /etc/fonts/${configVersion}/fonts.conf link to $out/etc/fonts/fonts.conf,
and other modifications should go to /etc/fonts/${configVersion}/conf.d
- See ./make-fonts-conf.xsl for config details.
