[JW Lua] FCSmartShapeSegment.BreakOffsetX can only be changed for hairpins if it had been manually changed before

[Jan Angermüller]

Jari,

if a smart shape segment from a hairpin with a line break doesn't have a 
(manual) BreakOffsetX (i.e. its value is 0), then a change to the 
BreakOffsetX doesn't "get active". I.e. the new value is stored, but not 
shown in the hairpin. I assume that there is a function like 
SetCustomOffset(true/false) missing especially for the BreakOffset. 
SetCustomOffset seems to effect EndpointOffset only.

See test code below (create a score with hairpin with a line break and 
select the area, then run the script).
The script writes new values to the BreakOffsetX values which are 
stored, but no visual change happens.

A similar problem seems to exist with the glissando BreakOffset (see my 
very old mail from the 3rd of February 2015).

Best,
Jan
