title: App Engine image resize without maintaining aspect ratio?
body: <p>When I call resize on images using app engine, they maintain their aspect ratio - I don't end up with the size I ask for.</p>
  
  <p>I'm trying to make rectangular pixel NTSC images from square pixel sources, so I don't want this behaviour</p>
  
  <p>I want to take an image that is 720x540 and resize it to 720x480 but what I actually end up when ask for the resize is an image that is 640x480.</p>
  
  <p>Is there any way round this?</p>
