Ah, that's nice! I don't know why i was so sure that they aren't. > The challenge here is how each of the glyphs get "heavier" or "lighter". > This is a non-trivial design problem.

I don't think we should require every font to have optical variants. best, Janek _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
