HTML 5 Canvas Library

So what about a library that you can use with the canvas items you are creating?

Here is “a basic HTML 5 canvas drawing library for those familiar with the java.awt.Graphics class in Java. It also comes with a JavaScript implementation of the game Breakout to demonstrate using the library.

Various utility methods will be added to this library over time to abstract away the low-level drawing methods found in HTML 5 canvas. Feel free to make requests to improve this library.”
