[JW Lua] Wrong CalcStemUp values on "Reverse up" notes?

[Jan Angermüller]

Jari et al,

I get wrong FCNoteEntry:CalcStemUp() results when I run this script on 
the attached document.

for e in eachentry(finenv.Region()) do
     print(e:CalcStemUp())
end

Instead of
true, true, false, false, true, true
the script prints:
true, false, true, false, false, false



The notes that have the "Reverse Up" flag set return the wrong result.

Best,
Jan
