Methods
b2.MouseJoint:getDampingRatio - returns the damping ratio
b2.MouseJoint:getFrequency - returns the response frequency in Hertz
b2.MouseJoint:getMaxForce - returns the maximum force in N
b2.MouseJoint:getTarget - returns the x and y coordinates of the target point
b2.MouseJoint:setDampingRatio - sets the damping ratio (0 = no damping, 1 = critical damping)
b2.MouseJoint:setFrequency - sets the response frequency in Hertz
b2.MouseJoint:setMaxForce - sets the maximum force in N
b2.MouseJoint:setTarget - updates the target point
