NAME
       s3d_pep_line_normals - add normals to lines

SYNOPSIS
       #include <s3d.h>

       int s3d_pep_line_normals(int object, const float *nbuf, uint16_t n);

DESCRIPTION
       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.
