title: Pixi - how to continue an animation when focus is lost?
body: <p>I have a pixi graphic, which I animate.</p>
  
  <p>I would like the animation ton continue even when the browser is minimised or the tab is no longer the "active" tab.</p>
  
  <p>How do I do this? Currently all animation is paused when the browser focus is lost?</p>
