title: How to have an infinitely big canvas?
body: <p>I am building a web app that uses a canvas to draw on. I would like to have an infinitly big drawing space (you can scroll as long as you want in any direction) AND save the data / images to a database.</p>
  
  <p>Something has been done similar to that here: <a href="http://wordsquared.com/" rel="noreferrer">http://wordsquared.com/</a>, where the more people that play it, the larger it gets.</p>
  
  <p>I know this would require somehow tiling images, saving them to a db, then only loding the ones within the viewport. How would this and the infinite scrolling be accomplished / where should I start?</p>
