[Bf-committers] [developer.blender.org] [Changed CC] T37798: Flip is drawn when I give scale of Bone a negative value with POSE mode.

[PerfectionCat]

@Campbell Barton:
Thank you very much for your advice.


I made data converter in python.
It was displayed as reported when I changed Armature type when I checked it because there was unjust processing.
Because I had not watched such a phenomenon in the past, I reported it.
I do not intend to use this intentionally.
In addition, I thank for having advised me to do appropriate inspection for scaling.
