texpdf, cjk issues not resolved

- ctex preferable to xeCJK? (if/when it works)
- note: the current round of texpdf changes relate
  to a bug report on the old live-manual
  for debian-live to wit:
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1052693
- apparently sisu-pdf does not produce latex
  suitable for the latest texlive (texlive-2023)
- some of the latex output changes here are from
  sisu:spine, the dlang version of sisu
