title: IE9 Float32Array error, while Firefox and Chrome are OK
body: <p>I created a game with playn version 1.1, using SurfaceLayer to draw Images into it.</p>
  
  <p>with the java backend no problem,
  with the html backend:
  Firefox OK,  Chrome OK,
  while using IE9 returns <strong>failed to init (reference error)  Float32Array</strong></p>
  
  <p>I'm using windows 7 64</p>
  
  <p>Thanks</p>
