Possible bug(s) with vertical alignment on Dynamics staff

[Peter Toye]

Please ignore previous mail - forgot to add the scores!

I'm trying to align dynamics with markup text in a Dynamics staff and have 
found several issues:

1. Just inserting the text by attaching it to a silent note using "^" or "_" 
works as expected. See examples 1 & 2

2. Trying "-" is the same as "_". This isn't documented, and probably shouldn't 
be. But it would be useful to have this syntax for horizontally aligned text. 
See example 3.

3. Tweaking the Y-offset by 0.0 using "_" appears to change it to having used 
"^" if you see what I mean. Example 4. Tweaking it to -0.6 gives the result I 
want. Example 5.

4. In the Internals manual, the unit for the Y-offset property is not 
mentioned. This wastes a lot of time in experimentation, especially given issue 
3!

Regards,

Peter
