title: How to scale on-screen pixels?
body: <p>I have written a 2D Jump&amp;Run Engine resulting in a 320x224 (320x240) image. To maintain the old school "pixely"-feel to it, I would like to scale the resulting image by 2 or 3 or 4, according to the resolution of the user. </p>
  
  <p>I don't want to scale each and every sprite, but the resulting image!</p>
  
  <p>Thanks in advance :)</p>
