[JW Lua] GetStaffPosition for a note entry ?

[Jari Williamsson]

Jan,

For now, you'd need to go through the percussion layout to get the 
position for percussion entries. I'll update CalcActualDisplacement() to 
work with percussion staves later, but it'll not be in the next update.


Best regards,

Jari Williamsson
