++ \brief Builds smooth vertex normals over a mesh.
++
++ - "smooth" because smoothing groups are not supported here
++ - takes angles into account for correct cube normals computation
++
++ To use 32bit indices pass a pointer in dFaces and set wFaces to zero. Alternatively pass a pointer to
++ wFaces and set dFaces to zero.
++
++ \param[in] nbTris Number of triangles
++ \param[in] nbVerts Number of vertices
++ \param[in] verts Array of vertices
++ \param[in] dFaces Array of dword triangle indices, or null
++ \param[in] wFaces Array of word triangle indices, or null
++ \param[out] normals Array of computed normals (assumes nbVerts vectors)
++ \param[in] flip Flips the normals or not
++ \return True on success.
