The font scan read /usr/share/fonts, /usr/local/share/fonts, ~/.fonts and the
XDG data folders. Packages add folders outside those to fontconfig's
configuration (TeX Gyre under /usr/share/texmf/fonts), so fc-list and other
apps showed fonts VectorCraft didn't have. The scan now also reads the <dir>
folders of /etc/fonts/fonts.conf and the files it includes (conf.d, the user's
own), as the fontconfig documentation describes them. The files are read as
they are: no library is linked and no program is run.
