OpenType in LilyPond

[Malte Meyn]

Hi list,

if I understand correctly LilyPond already supports OpenType features 
and this will be documented in the next version (changes already have 
been pushed to master). Is this only for use in markup \overrides or can 
you select features document-wide? This would be nice:

\paper {
  #(define fonts
    (set-global-fonts
    #:music "cadence"
    #:brace "cadence"
    #:roman "Vollkorn" % Can this be Vollkorn with OT feature ss13?
    #:factor (/ staff-height pt 20)
  ))
}

Thanks,
Malte
