title: Pygame and rotation of a sprite
body: <p>I've been playing around for a while now with the function <code>pygame.transform.rotate()</code>, <code>_get_rect()</code>, <code>_get_rect().center</code> and <code>_get_size()</code>.</p>
  
  <p>I have an image of an arrow that I want to rotate and I have trouble to understand what's going on.</p>
  
  <p>My question is from which point <code>(x,y)</code> is the rotation done?</p>
  
  <p>In my example I have an image of size 28x182 and I put at 200,100 with <code>screen.blit()</code>.</p>
