I forked it and gave the robot work to do through my structured way of things. Seems to be working so far, with some added extensions to the original: https://github.com/Keyframe/canvas_ity_c89

Blessings, this is exactly what I wanted when I saw the project. Please give my regards to the robot who helped. ;)
