title: NSOutline/NSTableView source list Lion-style icons
body: <p>From the Mac OS X HIG:</p>
  
  <blockquote>
    <p>As with the icons that can be used inside toolbar controls, the system applies various effects to sidebar icons. To help you understand how these effects can change the appearance of a sidebar icon, consider the Finder Home icon, shown here in its unprocessed state[...]</p>

  <p>So I'm trying to get my NSOutlineView to render a black sidebar icon with the typical new Lion style. I'm using a view-based NSOutlineView. However, I'm unable to find anything in the docs and if I simple set the imageView.image property to the sidebar image, it renders in black. So I figure there must be some sort of opt-in mechanism to get the sidebar to render it properly. Any suggestions on how to achieve that?</p>
