It's appreciably larger than the rounding error, which is in the region
of 1e-16 for a global-staff-size of 20, but small enough that it doesn't
interfere with smaller staff sizes.

I've tested this, but it breaks cross-staff and cross-voice arpeggios,
which tend to miss the desired notehead by a squiggle.
