- print/texlive-infra was renamed with print/texlive-tlmgr.
  Note that currently tlmgr(1) does not work because of
  lack of TLPDB.  This will be fixed.

- Lua libraries used in LuaTeX are separated into
  devel/tex-libtexlua and devel/texlibtexluajit.
  USE_TEX supports them via keywords "texlua" and "texluajit".

- libsynctex is currently installed by devel/tex-web2c.
  This will be separated into a single port.

- Add graphics/libpotrace and use installed libpotrace
  and libharfbuzz.
