For determining horizontal spacing it is necessary to know stem directions.
In the case of beams, stem directions are determined after doing
automatic knees.
It would probably be possible to revise the Beam::consider_auto_knees,
so it doesn't use the relative coordinates (which triggers
the vertical positioning).
I'll try using pure_relative_y_coordinate. Do you know what the problem is for cross-staff slurs and arpeggios?
