Javascript can hold full precision integers up to 2^53. Let's say you can mouve by 1024 pixels per seconds. It would take 2^53 / (3600 * 24 * 365.25) ~= 280 000

Javascript can hold full precision integers up to 2^53. Let's say you can mouve by 1024 pixels per seconds. It would take 2^53 / (3600 * 24 * 365.25) ~= 280 000 years to get beyond the limit. I think we are pretty safe on that part, even for veery long running app.
