# [NTG-context] optical bounds in ConTeXt

```Dear list,

I have the following sample:

\definefontfeature[default][default][protrusion=quality, opbd=yes]
\definefontfamily[mainface][rm][Linux Libertine O]
\setupbodyfont[mainface, 300pt]
\setuppagenumbering[location=]
\setupalign[hanging]
\showframe
\starttext
W
\stoptext

Optical bounds used to work with the previous ConTeXt versions, but I
cannot get them working with the new font reader (the explanation comes
from Hans).

Am I missing something or is it something to be implemented yet?
