I think performance is the biggest problem of ocanvas

I tried oCanvas a few days and found its so beautiful and elegant, and have a very small size.
But when I run some tests, the FPS makes me so disappointed(already set the fps to 60), especially on android phone.

Then I forked the project and checked the main loop in source code and found some setTimeout functions may slow down the fps, so I removed the fps setting and did some modification in main loop, sprite and animation, and then the fps looks improved a lot , I add some examples to compare the fps(https://github.com/keel/ocanvas/tree/develop/examples).

Also, I add loop and update paras to animate(), so I can make some special effect (examples/animation.html)

I really like oCanvas and hope it used widely, I don't think my work is good enough, so I suggest @koggdal can make some performance improvement , and add unit tests to make it more stable.

Thanks for considering oCanvas! :)

I don't have much time to work on this project anymore though, so for me this is mostly in maintenance mode. Most of the code is from 2012 or so.. :) I'd be happy to review a PR though in case you want to fix things up!
