title: Canvas not resizing automatically in WinJS
body: <p>I just ported my game to Win8JS. It was fairly simple surprisingly. But I made the game with a fixed resolution in mind. I have explicitly set a resolution of 800 x 500 pixels on all canvas elements but I want them to scale automatically to all resolutions on the simulator - how do I achieve that? </p>
  
  <p>This is how my game looks right now <a href="http://i.msdn.microsoft.com/dynimg/IC571329.png" rel="nofollow">http://i.msdn.microsoft.com/dynimg/IC571329.png</a>  :(</p>
  
  <p>On the same link <a href="http://msdn.microsoft.com/en-us/library/windows/apps/hh780612.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windows/apps/hh780612.aspx</a> </p>
  
  <p>it says "canvas automatically fills the empty space" but it doesn't in my case probably because I have pre defined fixed height and width? </p>
  
  <p>How do I go on about this? If I remove the width and height then the canvas won't be visible. Fairly new to all this - would appreciate help. </p>
  
  <p>Thanks! </p>
