[NTG-context] \tfx and \tf having the same size

7 Feb 2011

      Hello,

I have noticed that \tfx and \tf yield the same size. For example in the 
sample below:

\tfxx A\tfx A\tf A\tfa A\tfb A\tfc A\tfd A

However, the documentation states that tfx should be 0.8 size of tf.

Please, what did I get wrong?

Thank you. Best regards,
Tomas
