[JW Lua] FCTextRepeat.HorizontalPos scaling

[Jan Angermüller]

Jari,

the documentation to FCTextRepeat.HorizontalPos only says:
"Returns the horizontal position (in *EVPU*s) from the measure's origin."

Maybe it would be more clear if you could mention that it is a scaled 
value, depending on FCMeasure:GetWidth().
so if the measure width is 300, then 24 means the measure position 24 / 
300 starting from position 0 (i.e. where the music starts minus "Spacing 
Before Music").
Or in other words: a horizontalPos value of 24 means 24 * 
MeasureScalingFactor.

Best,
Jan
