title: Decrease indentation in TreeViewItem for deepest node
body: <p>How can I decrease the left indentation of the deepest <code>TreeViewItem</code> node? For some reason WPF seem to increase this indentation by quite a bit for all but the deepest node. Looking at Window XP's tree view implementation each depth has the same left margin.</p>
  
  <p>I've searched around and I can't seem to find an implementation that works <em>yet</em> it appears to be possible.</p>
