Currently updates to the frame buffer pain the pixels individually even though the painting can be expressed by a single line.

We should make a single line call with the two coordinates reducing updates and improving performance.

I'm not 100% sure that Bresenham's line algorithm will be more performant, but it's easy enough to test.
