-- jfm-shgtest.lua: a minimal JFM for the tests of showhanmengrid.
-- Every character belongs to class 0, and the JFM puts 0.25zw between
-- two of them (shibu-aki by the JFM, with \kanjiskip left at 0pt).
-- The boundaries of boxes and paragraphs get their own classes, so that
-- no glue is put before the first or after the last character.
