Bug 1467277 - Avoid getting zero normalized vector of rotate3d for animations. r=hiro If we have a rotate axis whose length is extremely large, we will get an infinite value, and its normalized vector is a zero vector, instead of an unit vector, i.e. (x/inf, y/inf, z/inf) == (0, 0, 0). The solution is: we scale the vector, so the length becomes a finite value, and we could get a valid unit vector. Therefore, we use a different normalization method, robust_normalize().
