[JW Lua] Slur metrics returns wrong values - problem identified

[Jan Angermüller]

Hi Chris and Jari,

That's the solution!
Although the interesting thing in this case is that the values of "Smart 
Shape Placement" are indeed correct here (it's a 12 EVPU distance).
It's only the calculated distance 
(FCSmartShape:CalcRightEntryMetricsPos) that returns the wrong value.
But if I add the "Avoid Staff Lines" value to the wrong value, it 
becomes correct.
Or: if I set the "Avoid Staff Lines" value to 0 (which doesn't change 
the slur visually), the calculated vertical metrics from 
CalcRightEntryMetricsPos are also correct.

So there must be a problem somewhere back in JW Lua or in the Plugin SDK 
that*accidentally adds the Avoid Stafff Lines values in this case.*

My workaround now: uncheck "Tips Avoid Staff Lines" or set the value to 0.

Best,
Jan
