As @dlazesz mentioned, I'll draw a tikz version of the figure. @sassbalint, xfig is great, but for me [tikzpicture](https://www.bu.edu/math/files/2013/08/tikzpgfmanual.pdf) is a bit easier to use. I try to do it...
@sassbalint No, I'm not OK with this :) I try to write it as clear as possible, hoping that later others can extend it without my help. But of course...
