serious (?) bug in Quaternion.slerp(Quat,Quat,float)

The Line

        if (q1.x == q2.x && q1.y == q2.y && q1.z == q2.z && q1.w == q2.w) {
            return q1;
        }



should be changed too

        if (q1.x == q2.x && q1.y == q2.y && q1.z == q2.z && q1.w == q2.w) {
            interpolated.set(q1);
            this.set(q1);
            return interpolated;
        }




I say serious in that this bug made me go crazy thinking I had done something wrong!! ;)

Yes, I agree. Changed and committed.
