   * HACK: Qt does not give the possibility to get the StyleSheet-specified color of a TabBar's Tab!
   * I need this color to paint the Close Button the same way the text looks! (Marketing order!)
   * It took me > 1h to dig through the Qt sources to find a way to GET the colors.
   * I found nothing that would be implemented in under 2 hrs.
   * So I will do this super bad but quick hack, and I will not fix that, ever. It works perfectly, though.
