okay - I have added a demo with some benchmarking to illustrate that the suggestions lead to lower average executions times for the draw() method - maybe not initially but eventually it becomes true.

add benchmark to provide proof

Thank you for the answer! I doubt calling the functions with .bind with help with the performance since .draw is only called once per iteration. The browser would optimize it out anyway so it's probably not worth doing these micro-optimizations, though I haven't done any benchmarking on that. Taking a look at my final solution (it's on my homepage), it seems that I solved the problem simply by not calling .rotate and .restore, and instead just do the calculations myself. Saving the entire 2D context is unnecessary, so I just avoided those methods and ended with sub-ms rendering time.
