/**
\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.
