In response to @lodimob. Thanks for this kata, Could you add to the description that fillll point that fall on lines are expected to do nothing? I add been confused on the last mixedDrawing tests if my mistake came from this and had to check here.
Also I agree as it as been said already, a bit more small tests cases with mixed drawing would help a lot for debugging. I just can't find what is wrong with my code since every simple test passes.

edit: I think my mistake come from the fact that I expected rectangle to be drawn from top left to down right, and the last test was the only one doing it in reverse manner.

Exactly! This was a very enjoyable kata. Here is another one like it : https://www.codewars.com/kata/515bb423de843ea99400000a
