reorder method
Resets the euler angle with a new order by creating a quaternion from this euler angle and then setting this euler angle with the quaternion and the new order.
Warning: this discards revolution information.
Implementation
Euler reorder(RotationOrders newOrder) {
// WARNING: this discards revolution information -bhouston
_quaternion.setFromEuler(this, false);
return setFromQuaternion(_quaternion, newOrder, false);
}
