       Adds normal information to lines, giving each vertex of a line a normal information. This makes lines
       somewhat nicer, you'll need that especially when you're going to build wireframe models.

       nbuf should contain n * 6 float values, for each vertex a normal vector (x,y,z), and you have 2 vertices
       for each line so that makes 6 float values per line in total.
