Adding ability to bind to buttons to custom interface elements, also use screen size detection to avoid using canvas on small devices since is more cpu intensive. Added version check for IE specific implementations to avoid using them for IE 9 and made most IE implementation differences a one-time process instead of an if/else which is evaulated on every call to the function.
