title: UIView rotated by 45° disappears?
body: <p>maybe I don't get. When I do</p>
  
  <pre><code>self.tweetPeak.transform = CGAffineTransformMakeRotation(RADIANS(45));
  </code></pre>
  
  <p>where RADIAN is</p>
  
  <pre><code>#define RADIANS(degrees) ((degrees * M_PI) / 180.0)
  </code></pre>
  
  <p>on a simple UIView Object it will disappear.</p>
  
  <p>I guess it's just to thin to see. My impression is that the view is getting smaller in a range between 20 to 45 degrees.</p>
  
  <p>What is it? I tried to set the view opaque. No effect.</p>
