I don't think limitations of a given tool are a valid excuse for an unsuitable product if tools are available that can do the required job. I don't know what OS you are using, but on Windows MS Paint would not have any problems drawing a multitude of geometrical shapes (including stars) on anything.
A well-placed Knight certainly is as good as anything else. But the issue is: how much effort does it take to place it well? Slow pieces are good defenders, but it takes an enormous investment to use them as attackers on a large board. And you would have to do that at some point, to launch an attack that can overcome the opponent's defenses. It is a similar problem as what makes Xingqi so drawish, in a less absolutr form: if a subset of the pieces is confined (in this case by inertia) to their own camp, an attacker is very much at a disadvantage.
