Re: bar number position (direction) numerical definitions overlap

[Mats Bengtsson]

I have submitted the following changes (the numerical values correspond to
the BarNumber object):

|side-axis| (number):
   |1|

If the value is #X (or equivalently 1), the object is placed 
horizontally next to the other object. If the value is #Y or 0, it is 
placed vertically.

|direction| (direction):
   |1|

If side-position is #X, then this property determines if the object is 
placed #LEFT, #CENTER or #RIGHT with respect to the other object. 
Otherwise, it determines if the object is placed #UP #CENTER or #DOWN.  
Numerical values may also be used. #UP=1, #DOWN=-1, #LEFT=-1, #RIGHT=1, 
CENTER=0 but also other numerical values are permitted.


I hope this will make it more clear. Note that printing the relevant 
interpretation
of the default value, such as "1 (#UP)" or "1 (#LEFT)" would be just as 
difficult
(if not more difficult) than being able to handle alternative text 
strings for the
same property in different objects (when I said it was "probably 
difficult" I
meant "with 99.9% difficult"). ;-)

Note also that you can use
\override Score.BarNumber #'direction = #-2
or
\override Score.BarNumber #'direction = #0.58
if you wish. I tried to clarify that aspect too in the text above.
