Resizes the canvas to a given width and height.
resizeCanvas() immediately clears the canvas and calls redraw(). It's common to call resizeCanvas() within the body of windowResized() like so:
function windowResized() {
resizeCanvas(windowWidth, windowHeight);
}
The first two parameters, width and height, set the dimensions of the canvas. They also the values of the width and height system variables. For example, calling resizeCanvas(300, 500) resizes the canvas to 300×500 pixels, then sets width to 300 and height 500.
The third parameter, noRedraw, is optional. If true is passed, as in resizeCanvas(300, 500, true), then the canvas will be canvas to 300×500 pixels but the redraw() function won't be called immediately. By default, redraw() is called immediately when resizeCanvas() finishes executing.
