%% test-keys.tex
%% =============
%% Key test (upLaTeX + dvipdfmx, LuaLaTeX + LuaTeX-ja): the keys given
%% as package options and with \showhanmengridsetup take effect.
%%
%%   uplatex test-keys.tex && dvipdfmx test-keys
%%   lualatex test-keys.tex
%%
%% What to check:
%%   * SHG-EXPECT OK: chars=30 and lines=20 override the computed
%%     values, so that there is an overflow in both directions.
%%   * SHG-POS OK on page 1.
%%   * In the PDF: no frame of the whole grid, no magenta overflow, red
%%     0.4pt lines, 30 x 20 squares.
