/**
 * When using a fixed framerate, Threlte is interpolating the position and
 * rotation of RigidBody objects. Sometimes, this is not desirable, especially
 * when using methods on the rigidbody that teleport the object, e.g. should
 * lead to a sudden change in translation/rotation such as `rb.setTranslation`.
 * These methods are overridden to reset the physics simulation position and
 * rotation to the current object position and rotation.
