[JW Lua] Hidden Finale feature: object rotation

[Jan Angermüller]

I just noticed an interesting hidden Finale feature which I haven't seen 
before:
JW Lua scripts can rotate any object from the Shape Designer.

If you want to do this manually in the original Finale Shape Designer, 
it is very tricky as only arrowheads can be rotated by default. So you 
have to design custom arrowheads, create invisible lines and then rotate 
awkwardly with the mouse to get a rotated result.
In JW Lua the FCShapeDefInstructions commands AddStartGroup and 
AddStartObject come with a transform and rotation parameter by default, 
so it's even easy to enter the rotation angle directly.

Here is a short screencam video that shows tilting a Maestro clef for 
avoiding clef collisions in condensed scores: the top clefs are rotated 
by 0.06°, the bottom clefs are not rotated and still collide.

Best,
Jan
