title: Changing my CALayer's anchorPoint moves the view
body: <p>I want to alter the <code>anchorPoint</code>, but keep the view in the same place.
  I've tried <code>NSLog</code>-ing <code>self.layer.position</code> and <code>self.center</code> and they both stay the same regardless of changes to the anchorPoint. Yet my view moves!</p>
  
  <p>Any tips on how to do this?</p>
  
  <pre><code>self.layer.anchorPoint = CGPointMake(0.5, 0.5);
  NSLog(@"center point: %f %f", self.layer.position.x, self.layer.position.y);
  self.layer.anchorPoint = CGPointMake(1, 1);
  NSLog(@"center point: %f %f", self.layer.position.x, self.layer.position.y);
  </code></pre>
  
  <p>The output is:</p>
  
  <pre><code>2009-12-27 20:43:24.161 Type[11289:207] center point: 272.500000 242.500000
  2009-12-27 20:43:24.162 Type[11289:207] center point: 272.500000 242.500000
  </code></pre>
