Perhaps it could be used, as proposed earlier, to calculate the weigthed
average of the normal vectors instead of just the average.
It makes sense that the normal vector of a larger triangle has more
effect in the normal of the vertex than a smaller triangle.
Of course doing it this way can result in degenerate triangles, which
is a problem.
