%% test-jfm.tex
%% ============
%% Character pitch test with a JFM (LuaLaTeX + LuaTeX-ja): the design of
%% test-kanjiskip.tex, but the 0.25zw between characters comes from the
%% JFM (jfm-shgtest.lua) and \kanjiskip is 0pt.
%%
%%   lualatex test-jfm.tex
%%   lualatex -jobname=test-jfm-natural "\def\PITCH{natural}\input test-jfm.tex"
%%
%% What to check:
%%   * SHG-EXPECT OK: 41 chars (pitch=zw) or 33 chars (pitch=natural) x
%%     33 lines, no overflow.
%%   * SHG-NOTE OK: "character pitch = 1.25zw, not 1zw (\kanjiskip =
%%     0zw, JFM +0.25zw)".
%%   * SHG-POS OK, as in test-kanjiskip.tex.
