Vector normalization function

Hi, the following function:

static Vec2 norm(Vec2 const & v)
    {
        if(length(v) < 1e-30)
            return {0.0f, 0.0f};
    }

doesn't return a vector when length(v) >= 1e-30. I suggest adding the following return statement:

static Vec2 norm(Vec2 const & v)
    {
        if(length(v) < 1e-30)
            return {0.0f, 0.0f};

        return v / length(v);
    }
