I am experimenting with the pdftex features (margin kerning and font expansion). So far I have only been able to make margin kerning to work. Now I tried font expansion but couldn't note any difference to what I have before. I set


and for the font I set the parameters to (for example)

  f.parameters.stretch = 30
  f.parameters.shrink  = 20
  f.parameters.step    = 10
  f.parameters.auto_expand = true

(where f is the font object for font.define(f))

Without posting a complete minimal example: can someone tell me if these parameters look OK or if I am missing anything "obvious"?
