title: How to wrap blit around screen edge?
body: <p>Given an image, how could one "wrap" that image around the screen?</p>
  
  <p>For example, if you set the image's rect style object below the screen edge- the invisible half would blit onto the top of the screen.</p>
  
  <pre><code>imageRect.top=800 #Below screen edge
  screen.blit(image,imageRect) #Blit on both sides of the screen
  </code></pre>
  
  <p>Is this by any ways possible (in pygame)?</p>
