Crud Factory Fontconfig
-----------------------
Differences from freedesktop.org Fontconfig:
* Property priority order can be set in XML, for example:
<priority>
<name>family</name>
<name>style</name>
</priority>
The default duplicates the hardcoded settings of freedesktop.org
Fontconfig 2.8:
<priority>
<name>foundry</name>
<name>charset</name>
<name>family</name>
<name>lang</name>
<name>family</name>
<name>spacing</name>
<name>pixelsize</name>
<name>style</name>
<name>slant</name>
<name>weight</name>
<name>width</name>
<name>decorative</name>
<name>antialias</name>
<name>rasterizer</name>
<name>outline</name>
<name>fontversion</name>
</priority>
* Preferred family/style and WWS family/style are kept distinct
from the "normal" family/style and each other. For
TrueType/OpenType fonts, the preferred names and/or WWS names
need not be explicitly present in the font; Crud Factory
Fontconfig will use fallback values. Thus, very often, the
"normal", "preferred", and "WWS" names are the same.
By default one works with the "normal" family/style. To work
with WWS family/style instead, try
<match target="scan">
<test name="wwsfamily" compare="not_eq" target="font"><string></string></test>
<edit mode="assign" name="family"><name>wwsfamily</name></edit>
<test name="wwsstyle" compare="not_eq" target="font"><string></string></test>
<edit mode="assign" name="style"><name>wwsstyle</name></edit>
</match>
This will cause family/style to be replaced with WWS
family/style at scan time. For almost all current fonts (in the
year 2010) this won't make any difference. What would make a
difference is to use the preferred family/style instead of the
WWS values; unfortunately GIMP, Inkscape, and probably many
other programs would end up severely broken, because they make
assumptions about font names that do not apply to preferred
names. Indeed, the frequently used free software library, Pango,
employs an abstract model of fonts that, if not augmented,
is incompatible with preferred names.
(Freedesktop.org Fontconfig's font matcher not only employs
preferred names, thus breaking all Pango-based programs, but
freely mixes preferred family with "normal" style, WWS style
with preferred family, and so on. Choosing fonts from large,
complex families becomes like the spin of a roulette wheel.)
