OK, I have added a collect_opentype_fonts script to my
python_fontconfig examples
<https://gitlab.com/ldo/python_fontconfig_examples>,
<https://github.com/ldo/python_fontconfig_examples>. This gets all
known font directories from Fontconfig, rather than scanning a
hard-coded set of directories, but it still uses HarfBuzz to query the
OpenType font features.
