wrong stem lengths for smaller sized staffs

[Werner LEMBERG]

I've extended my test file.  Please have a look at the last two beats.

% . There should be a mechanism to give the staff size in a \with {...}
%   block with a single command, covering all parameters.  Perhaps a
%   new `set-staff-size' scheme function?
%
% . Current documentation says that changing the `fontSize' and
%   `StaffSymbol' properties is sufficient.  Unfortunately, it is not:
%
%   1. Stems under beams have wrong lengths sometimes.
%
%   2. Dynamics have a different relative size.
%
%   3. I'm not sure whether the thickness of staff lines really should be
%      the same in both the bigger and the smaller staff.  Thicker than
%      normal is correct, but that thick?  The problem is that the
%      thickness of beams must be smaller; this reduces the contrast
%      between beams and staff lines.
%
%   4. A similar problem for stems.  The stem thickness is too big IMHO
%      compared to note heads.
