# - Check minimum freetype & other deps on bumps. See
#   https://gitlab.freedesktop.org/fontconfig/fontconfig/-/blob/main/configure.ac#L314.
#   Note that FT versioning is confusing, need to map it using
#   https://git.savannah.gnu.org/cgit/freetype/freetype2.git/tree/docs/VERSIONS.TXT
#   But sometimes it's actually greater than that, e.g. see Fedora's spec file
#   https://src.fedoraproject.org/rpms/fontconfig/blob/rawhide/f/fontconfig.spec#_1
#
# - Purposefully dropped the xml USE flag and libxml2 support. Expat is the
#   default and used by every distro. See bug #283191.
#
# - There's a test-only dep on json-c.
#   It might become an optional(?) runtime dep in future though. Who knows.
#   Keep an eye on it.
