Please don't do this. When installing fonts via package manager (dpkg, apt,
yum, whatever) they will install new font, and set the timestamp to packaging
time, but the directory mtime is updated.
If possible use individual file's mtime and size, and compare against values
stored in cache. If either differs, the font file is dirty and needs
recalculation.</pre>
