title: NSOulineView header cell font
body: <p>I'm trying to reduce the font size of the Header Cell in a <code>NSOutlineView</code> (source-list view-based). The problem is that using IB doesn't work for me (both modifying the font for <code>NSTextField</code> and <code>NSTextFieldCell</code>).</p>
  
  <p>The views are returned by <code>outlineView:viewForTableColumn:item:</code> using <code>makeViewWithIdentifier:owner:</code></p>
  
  <p>Any ideas?</p>
