1. Context method - enables you to restore specific contexts saved throughout the app so that you can pass in a variable that contains it and return the context restoration.



2. renderToCanvas - method that is reusable for doing off-screen rendering of images and slower performing tasks so they can be returned and drawn to the main context easily.

var renderToCanvas = function (width, height, renderFunction) {
    var buffer = document.createElement('canvas');
    buffer.width = width;
    buffer.height = height;

/* Better: */  x = x || y;    // logical OR.
