title: WebView with small scroll bars - how?
body: <p>I'm putting a WebView in an NSPanel and would like it to use small scroll bars.
  How do I tell it to? (Can't be done in Interface Builder)</p>
  
  <p>I realize a WebView has a number of different types of subviews, depending on the content that's loaded. But suppose I'm loading a web page with no frames. What view would contain the main vertical scroll bar? Is there an NSScrollView somewhere or is this managed differently?</p>
