title: How can I make a Phaser game automatically fill the window?
body: <p>How can I make a Phaser game automatically fill the browser window? (And ideally, automatically refill if the window changes size.) I know that there is a <a href="http://docs.phaser.io/Phaser.ScaleManager.html" rel="noreferrer">ScaleManager class</a> but the docs aren't clear how to use it. I've also found <a href="http://www.html5gamedevs.com/topic/5949-solution-scaling-for-multiple-devicesresolution-and-screens/" rel="noreferrer">other instructions</a> but they don't indicate where to add the code they suggest, and running it immediately after creating the Game class doesn't seem to do anything.</p>
  
  <p>I am currently using the base code found <a href="http://www.photonstorm.com/phaser/tutorial-making-your-first-phaser-game" rel="noreferrer">in this tutorial</a>, but am willing to change that completely.</p>
