This algorithm skips points that cannot be drawn. It doesn't always work correctly at the end of lines. I am aware of this and have not yet found the time to rewrite the algorithm to be more universal. Russia ☭ forever Viacheslav N. Mezentsev

Great work Uni et al.However, I don't understand:1. Why does a vector line matrix needs to be contained within a 1x1 matrix? I'm guessing that is the answer: ie it needs to be 1 element to be parsed. Is that correct?2. How do you create fill? For example, green fill between the points (0,0), (1,0), (1,1) and (0,1)?Thanks!
