Subject: Show how to properly support the Gonville font.
X-Git-Tag: release/2.13.16-1~54
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=c5ba96d235fb8c532773030cb44a641d5e23dff7;p=lilypond.git

Show how to properly support the Gonville font.

Example in input/gonville.ly; it is not part of the regtest, since we
currently do not ship Gonville.  This still does not work for alphabet
glyphs, since those are still hardcoded to feta-alphabet, and are
loaded through Pango.
