Anchor and ConnectedAnchor Gizmos are shown in incorrect position when "Swap Bodies" in "Configurable Joint" is active

Physics

-

How to reproduce:
1. Open attached project "PhysicsTestProject.zip" and scene "SampleScene"
2. Enter Play mode
3. In Scene view, observe anchor gizmos

Expected result: the gizmos are drawn in the middle of "HAND" object
Actual result: the gizmos do not take into account "Swap Bodies" value in "Configurable Joint", therefore, are always drawn in the same position

Reproducible with: 2017.4.27f1, 2018.4.1f1, 2019.1.4f1, 2019.2.0b3, 2019.3.0a3

    Resolution Note (fix version 2021.1):

    The swapBodies feature is behaving as designed. The swap occurs in the physics internals between two PhysX actors and axes of the rigidbodies in the joint. The calculation order of the rigidbodies influences the physics when swapBodies is enabled or disabled. The anchor Gizmos do not change in this swap. There is no visual change in the scene view when this field is toggled.

    The documentation for 2021.1.0a1 has been modified to better explain this.
