feature request: Add support for XDG_DATA_DIRS
Hello,
The XDG base directory specification (https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html) defines the XDG_DATA_DIRS as "a set of preference ordered base directories relative to which data files should be searched".
fontconfig currently only supports the XDG_DATA_HOME XDG environment variable, which is user-specific and can only include a single location.
Honoring XDG_DATA_DIRS would allow for fonts discovery on system where following the File Hierarchy Standard (FHS) is not practical (such as GNU Guix, NixOS, etc.)
Thank you for your consideration!
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
