How far the bone may swing anticlockwise of the baseline, in [0, PI].
How far the bone may swing clockwise of the baseline, in [0, PI].
What clockwise and anticlockwise are measured from.
The baseline for a GLOBAL joint - a world direction. Unit length. Unused when LOCAL.
A joint's rotational limits: a wedge about a baseline.
Angles are in radians, and a limit of PI means unconstrained in that direction. Anticlockwise is positive, matching vec2.signedAngle.
