-- There can be multiple treatments.lfg files in the tree and all are loaded in
-- the order specified by tree order access. The first treatment of a file
-- always wins, so one can overload. These files are not (to be) loaded with
-- font definitions. (Experiment as part of writing the font manual.)
--
-- So there are several ways to fix a font: add a patcher to a goodie file and
-- load that one. Such a patch can end up in the cached file. Treatments are
-- applied at runtime. An experimental auto-loaded goodie approach is not yet
-- enabled and will never be if treatments can do the job.
