/// This function can help improve the visual appearance of a surface patch by
/// smoothing normals with other nearby normals. It iterates over each triangle
/// in the surface patch and determines the sum of its corners normals. For any
/// given vertex, these sums are in turn summed for any triangles which use the
/// vertex. Usually, the resulting normals should be renormalised afterwards.
/// Note: This function can cause lighting discontinuities accross region boundaries.
