Nit: No else after return.  Do this:

  int icon_id = GetIconID();
  return (icon_id == -1) ?
      NULL : &ResourceBundle::GetSharedInstance().GetNativeImageNamed(icon_id);

[gone, 2013/05/14 17:50:17]

Done.

+    return &ResourceBundle::GetSharedInstance().GetNativeImageNamed(
+        GetIconID());
