Wheel joint definition. This requires defining a line of motion using an axis and an anchor point. The definition uses local anchor points and a local axis so that the initial configuration can violate the constraint slightly. The joint translation is zero when the local anchor points coincide in world space. Using local anchors and a local axis helps when saving and loading a game.
