%% test-tombo.tex
%% ==============
%% Trim marks (tombo) that move the page: the grid must follow the text.
%% \CLS is the class, \OPT its options and \PKG a package that adds the
%% trim marks (all optional; the default is jbook[tombo]).
%%
%%   platex  "\def\OPT{tombo}\def\CLS{jbook}\input test-tombo"
%%   platex  "\def\OPT{tombo}\def\CLS{jsbook}\input test-tombo"
%%   uplatex "\def\OPT{tombo}\def\CLS{utbook}\input test-tombo"
%%   uplatex "\def\CLS{ujarticle}\def\PKG{gentombow}\input test-tombo"
%%   lualatex "\def\CLS{ltjsarticle}\def\PKG{gentombow}\input test-tombo"
%%   platex  "\def\CLS{jlreq}\def\PKG{jlreq-trimmarks}\input test-tombo"
%%   lualatex "\def\CLS{jlreq}\def\PKG{jlreq-trimmarks}\input test-tombo"
%%
%% The tombo option of jclasses and jsclasses (\iftombow of pLaTeX) moves
%% the page by 1in in both directions in \@outputpage, while gentombow
%% (with LuaLaTeX) and jlreq-trimmarks move it with \hoffset/\voffset.
%%
%% What to check:
%%   * SHG-POS OK on pages 1 (odd) and 2 (even).
