Does anybody know why the top and the bottom of the bounding box of
the 'Flat' glyph, contrary to 'Sharp' and 'Natural', don't coincide
(more or less) with the extrema of the glyph's outline? A small
overshoot outside of the box make sense (although Feta doesn't handle
this consistently), but the opposite, that is, additional whitespace
within the box, looks rather pointless...
I think the whole bbox should be shifted down.
Note that accidentals with arrows have a similar problem: the bounding
box side near the tip of the arrow should be closer.
