title: CGAffineTransform scaling subviews issue
body: <p>Is there an easy way to tell CGAffineTransform not to scale frames of the subviews of a scaled view? view.autoResizeMask = false doesn't seem to work in this case. The only thing that is kinda "working" is reversing the transformation for subviews, like </p>
  
  <pre><code>for subview in view.subviews {
      (subview as! UIView).transform = CGAffineTransformInvert(view.transform)
  }
  </code></pre>
  
  <p>However, this takes 10 times longer in terms of computational time and is not quiet flexible. Does somebody know any other more efficient way, to scale the origins of the frames, but no their bounds ?</p>
