Comment 24 for bug 977980

>I think #19 brings a very good argument why 1 triangle must be used for fish. I suggest using 1 triangle for everything (like Janosch did it already) and see if that 'feels weird' and only then make the rules more complex.

OK, one triangle should be enough - after some thinking I agree.... But in Janosch's branch is not made that way AFAIK, it check trianges down and right
