Hmm, I suspect that this might be too slow on a system with a lot of fonts,
because it's going to have to scan all of the font directories.  I'm going to
try to patch FcConfigNormalizeFontDir to do a scan if it actually needs to; I
think that should limit the hit in performance to the cases where it actually
has to do the scan.
