[NTG-context] LuaMetaTeX: \hbox dir vs. direction

[Henri Menke]

Dear Hans,

In LuaMetaTeX the directional syntax for boxes

    \hbox dir TLT {...}

is no longer supported.  Currently this is necessary for PGF because certain
things like shading have to always be typeset in TLT.  Is there a simple
workaround?

Cheers, Henri
