Oh, I see! No need to go trough the markup interpretation since markup
commands should return a stencil.
Beware though that without ly:stencil-translate-axis, the symbol will
not be centered above the note but centered around the the left edge of
the note, it seems... is there a way to (in the scheme above) make sure
the stencil is centered above the note/chord that the markup is attached
to?
