[JW Lua] FCSmartShapePrefs:SetEngraverSlurSymmetryPercent doesn't work

[Jan Angermüller]

Jari,

FCSmartShapePrefs:SetEngraverSlurSymmetryPercent(...) doesn't work, but 
using FCSmartShapePrefs.EngraverSlurSymmetryPercent instead works fine.

Code snippet:

local slurprefs=finale.FCSmartShapePrefs()
slurprefs:LoadFirst()
slurprefs.EngraverSlurSymmetryPercent=500
slurprefs:SetEngraverSlurSymmetryPercent(700)
slurprefs:Save()
print(slurprefs:GetEngraverSlurSymmetryPercent()) --prints 500, not 700

Running [Unnamed Script] ======>
500
<======= [Unnamed Script] succeeded (Processing time: 0.000 s).

Best,
Jan
