a black diagonal line problem (and a simple solution)

[patakk]

First, thank you for this project, it is golden.

Anyway, the first time I tried to use it, it worked as expected, except the black diagonal line in the final render, as if the plane that rendered has a black stroke style and its two triangles' edges got rendered (that's my assumption).

I don't know if I'm correct in my assumption, but the easy fix for me was to add a noStroke() call in the draw() method.
