Sorry for the delay... took me some time to figure out why there was an 
error with cross-staff right-side Y coordinate after porting the logic 
from C++.  I think it's all working as expected, and I have added a few 
new test cases.  (NOTE: I only have 2.22.0 here, so I had to fixup the 
version statement.)  The one thing I did not include was adjusting the 
line ends for the arrows, but I assume the crosses would be best put at 
the arrow points anyway.

There is something to note in the original logic.  If the padding is 
large enough that the line spanner would disappear, then the stencil 
returned is null.  I am also likewise returning the empty list instead 
of a point-pair, so the code that consumes the results would need to 
check for this case.
