title: How do I paint the treeview node +/- buttons outside a treeview?
body: <p>Similar to the <code>ButtonRenderer</code> class, I want to be able to paint the +/- buttons used in <code>TreeViewNodes</code> completely separately to any instance of a <code>TreeView</code>. There doesn't seem to be a <code>ControlPaint</code> method that does it, and drawing a Button doesn't look right. Where can I get the drawing code for a treeview node from?</p>
