40\brief Builds smooth vertex normals over a mesh.
41
42- "smooth" because smoothing groups are not supported here
43- takes angles into account for correct cube normals computation
44
45To use 32bit indices pass a pointer in dFaces and set wFaces to zero. Alternatively pass a pointer to
46wFaces and set dFaces to zero.

50\param[in] verts Array of vertices
51\param[in] dFaces Array of dword triangle indices, or null
52\param[in] wFaces Array of word triangle indices, or null
53\param[out] normals Array of computed normals (assumes nbVerts vectors)
54\param[in] flip Flips the normals or not
