title: Tween large bitmap without lag
body: <p>I'm using a 3800x3000 bitmap as a background of a game.</p>
  
  <p>Now, I first show the whole bitmap - the landscape -, and than zoom in at the characters.
  I'm using TweenMax from GreenSock, but even with this advanced tween class my bitmap doesn't move and scale smooth.</p>
  
  <p>Any ideas how to solve this? I'd like to work with smaller bitmaps too and scale them, but than I'll lose the quality, and I can't blur the bitmap to hide the quality loss, since there's a terrain in the bitmap too, and I don't want to blur that.</p>
