optical bounds in ConTeXt

optical bounds in ConTeXt

[Pablo Rodriguez]

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?

Many thanks for your help,

Pablo

i'll check it but keep in mind that this font only has a few (so 
actually it's useless to rely on it's opbd) so i wonder if there are 
better tests

Many thanks for the good news, Hans.

Some time ago, I modified GFS Baskerville with random values for the
left and right optical bounds in some uppercase Greek letters with
diacritical marks (ἨἮἯὩ).

Just in case it helps, I attach it to this message.

Many thanks for your help,

Pablo
