[JW Lua] Glissando over system break ignores BreakOffsets

[Jan Angermüller]

Jari,

in addition to my "glissando positioning error" mail from two weeks ago 
(see below), I can add:
1.) I haven't solved the problem yet: a Lua-added glissando smartshape 
always appears at a completely wrong position in the score when all 
offsets are set to defaut (=0). But I found a workaround: if I use 
custom offsets, I can navigate the glissando to where I want them.

2.) I noticed another issue with a Lua-added glissando smartshape.
If it is a glissando "over system break", the 
FCSmartShapeSegment.BreakOffsets don't work:
a.) After the JW Lua creation of the glissando it appears "going up to 
the sky" at the end of the system (see screenshot 1).
But: when I grab it manually (no shifting, just clicking the middle 
control point and releasing it), it suddenly appears correctly.
Is there a visual update flag missing ? (see screenshot 2)

b.) It seems to be not possible to correct this in JW Lua code. I can 
change the FCSmartShapeSegment.BreakOffset, but nothing changes visually.
Again a visual update flag missing ?

Best regards,
Jan
