Normalize Zero Vector?

[DiamondToaster]

I know that, but as the documentation for the Vector3d class says: Changes this vector so that it keeps current direction but is exactly 1 unit long. FIXME: Fails for a zero vector. If you set the coordinates for a vector, let's say, Direction. If you set each of Direction's coordinates to 0 then call Direction:Normalize(), the distance and each component become NaN when they should stay at 0.
