       s3d_pep_line_normals - add normals to lines


       #include <s3d.h>

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


       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.
