title: Pygame zooming/scrolling window
body: <p>Im currently working on a project with pygame and am in need of being able to view part of a surface, moving around, zooming in and out ect</p>
  
  <p>Can anyone recommend a way of achieving this efficently, i have it working in a convoluted method at the moment but it is too slow and reduces the game to about 1fps when zoomed out to view the whole area. (my version of only scrolling and no zooming works fine with no lagging)</p>
  
  <p>Looking though the docs pygame.transform.scroll looks promising but i am unsure how i would correctly implement it with pygame.transform.scale for zooming in and out</p>
  
  <p>Any help welcome</p>
  
  <p><strong>update:</strong>
  I fiddled around for a bit and got it working scaleing objects and their positions before bliting them. I have now hit the problem that the scaling looks unatural because of the low resolution of the pygame scroll wheel events so I am now trying to impliment some kind of smoothing.</p>
