Dynamics negative Y-offset

[Simon Albrecht]

Hello everybody,

in the attachment you’ll find an example for a function which I use to 
make dynamics slightly overlap with staff lines for saving space. It 
used to work up to 2.19.8, but now (tested with 2.19.15 and .16) 
negative values of Y-offset remain without effect inspite of 
outside-staff-priority being unset.
Can anyone tell me how to update the function? (It should be 
backward-compatible.)

Thanks in advance,
Simon
