Redstone line rendering using Bresenham's line algorithm

This is a Redstone line rendering gpu which can generate straight diagonal lines between any two points on a diplay. The coordinates for two points are inputted in binary and the machine generates a line between them using the bresenham line algorithm. Each point is generated in 8 ticks, which means it generates pretty fast. It is also completely pistonless and command block free. It can be used to create images using straight lines, such as the star shown above.
