[NTG-context] no effect of \definefontfeature for adobevariablefontprototype

[garulfo]

Hi,

trying to work with variable fonts, I am stuck at the very beginning.

I can't see any effect of weight parameter.
Using adobevariablefontprototypebold and adobevariablefontprototypelight is working.

\starttext

\definefontfeature[whatever][axis={weight:150}]%
\definedfont[name:adobevariablefontprototype*whatever]foo@bar

\definefontfeature[whatever][axis={weight:350}]%
\definedfont[name:adobevariablefontprototype*whatever]foo@bar

\definefontfeature[whatever][axis={weight:550}]%
\definedfont[name:adobevariablefontprototype*whatever]foo@bar

\definefontfeature[whatever][axis={weight:750}]%
\definedfont[name:adobevariablefontprototype*whatever]foo@bar

\stoptext

Can it be something from with my font file ? 

Thanks,
Garulfo
