@brief Get the joint anchor point, in world coordinates.
This returns the point on body 2. You can think of a ball and socket
joint as trying to keep the result of dJointGetBallAnchor() and
dJointGetBallAnchor2() the same. If the joint is perfectly satisfied,
this function will return the same value as dJointGetBallAnchor() to
within roundoff errors. dJointGetBallAnchor2() can be used, along with
dJointGetBallAnchor(), to see how far the joint has come apart.
