Freehand Line Algorithm

Harold Cohen's Freehand Line Algorithm (c. 1971), implemented by Paul Cohen.
Mazes generated from Paul Cohen's reconstruction of Harold Cohen's lost Mazes code.

To render a drawing with the Freehand Line Algorithm, specify each line by its endpoints: [x0, y0, x1, y1] as shown in the Custom option.
