title: How is the relation between UIView's clipsToBounds and CALayer's masksToBounds?
body: <p>A <code>UIView</code> has a <code>CALayer</code>. That's pretty sure. But both seem to provide something that means the same thing.</p>
  
  <p>If I'd set <code>clipsToBounds=YES</code>, would this also set the layer's <code>masksToBounds=YES</code>? Why different names? Anyone knows?</p>
