[JW Lua] Calculating the slur metrics when a slur goes over several staff systems

[Jari Williamsson]

Jan,

Smartshapes over multiple systems creates additional data objects of the 
FCSmartShapeSegment class.

I don't have good documentation on smartshapes on my end, so it's lots 
of trial-and-error for me.


Best regards,

Jari Williamsson
