  *
  * \short A class to provide rendering of KDE icons.
  *
  * Currently, this class is not much more than a wrapper around QIconEngine.
  * However, it should not be difficult to extend with features such as SVG
  * rendered icons.
  *
  * Icon themes specifying a KDE-Extensions string list setting, will limit
  * themselves to checking these extensions exclusively, in the order specified
  * in the setting.
