title: Prevent UILabel from clipping it's text when the font size is larger than the label height
body: <p>I have a circumstance in my app whereby a label may be given a font size greater than it's height. This is to do with some rather complex architecture and layout code. Normally I would increase the label's height to accommodate the larger font but that is profoundly difficult to do in my scenario and I would rather avoid it.</p>
  
  <p>The next logical thing is to turn <code>clipsToBounds</code> off, to allow the text sublayer to overflow the bounds of the label. Unfortunately this seems to have no effect in this case as the text is still clipped.</p>
  
  <p>Am I missing something?</p>
