Can you list these 14 fonts, which of these 35 fonts are "the 14
required"?

I am not proposing to drop the gsfonts dependency completely, but I
would like to be changed to "gsfonts | ttf-dejavu" if possible. If some
other fonts would meet the criteria of the 14-font Postscript standard,
these could be added as alternatives too.
