Thank you and Dan for the excursion into weights in MetaFont!

Are these weights actually rendered as grey colours in the final font?
Or are they converted to black/white at a later stage?  I have looked
into the section on MetaFont in Kopka's 'Erweiterungen' in 'LaTeX', Vol.
2 (in German), but didn't found anything about weights.

Best regards,

until now (for no reason)
