title: Custom widget shapes in SWT
body: <p>I'm trying to work out how to make SWT widgets (e.g. Label, Frame) be some shape other than rectangular.</p>
  
  <p>I've made a custom shaped main window using the setRegion() method. Now I would like the widgets in the window to follow the same shape. I've tried using the setRegion() method on the widgets themselves (they inherit it) but nothing happens.</p>
  
  <p>How do I make an SWT widget have a custom shape?</p>
