title: Using texture during window resize
body: <p>So what I'm trying to do is copy the current front buffer to a texture and use this during a resize to mimic what a normal window resize would do. I'm doing this because the scene is too expensive to render during a resize and I want to provide a fluid resize.</p>
  
  <p>The texture coping is fine, but I'm struggling to work out the maths to get the texture to scale and translate appropriately (I know there will be borders visible when magnifying beyond the largest image dimension).</p>
  
  <p>Can anyone help me?</p>
