[Bf-committers] BONE which turned inside out

[Campbell Barton]

We had a bug report recently where the same effect happens if the
camera has a negative scale.

This could be detected (is_negative_m4), to draw it correctly, Since
we already do this with objects.

However negative scaled bones are likely to cause problems elsewhere,
IMHO its OK to have slightly odd drawing as a hint that you do
something really unsupported (or at least likely not to work as you
would want).

For example (assuming you wanted a flipped bone) constraints
CopyRotation and TrackTo, will remove flipping.
