Re: bar numbers at beginning of bar - partial solution

[Trevor Daniels]

The notes in the bar are displaced to avoid a collision
of the stem of the first note with the bar number.  A
potential solution is to use 'outside-staff-priority
with the priority of the bar number greater than the stem.
By default the 'outside-staff-priority is not set for the
Stem object, but even when set this doesn't work. Maybe the
Stem object does not honour the 'outside-staff-priority value,
as it has already moved itself horizontally to avoid the
collision before the skyline code is invoked.

(You would also need to move engravers to make the
'outside-staff-priority comparison between bar numbers and
stems work - see Learning Manual 4.4.3 for details - but
this doesn't help anyway and would give rise to other
problems.)

So the best solution is to lower the bar number by setting
the value of the 'staff-padding of the bar number object
sufficiently high to clear most of the stems, and tweaking
the value for any bar number for which the default gives a
poor result.
