What would the optimizations be for a larger canvas?

Does it redraw the whole canvas when an update is made* to a single line when there are several other lines on the canvas?

It doesn't redraw the whole canvas. The optimizations are really needed when 'filling' a shape. If you draw a large polygon, it may take a little longer to fill it with bricks. Optimizations can be made by using WebGL instead.
