I think that I can make fontconfig load all fonts to put them in the
global cache.  But maybe it's not such a disaster to have the *global*
cache be dependent on the config files; it might beat the alternative,
which is to load all fonts into memory and then filter through
FcConfigAcceptFont afterwards on each run.

Per-directory caches are always independent of the configuration.
