However, 18kB savings in the source code are no relevant advantage. The original image has a clear internal structure for simple reusability. It contains useful meta information. The approximation of lines by straight segments is the most simple one, and it is more precise than the "simplified" version with Beziers. Note e.g. that the arrows should be centered on each line.
