  // About AddBulletEx:
  // Parameters of this method are similar with parameters of
  // AddPictureEx and AddControlEx:
  // 1st parameter: name of bullet. Allows to hold additional text information
  //  together with bullet. There is no predefined meaning of this
  //  parameter. May be it will be used to display hints in future.
  // 2nd parameter: index of image
  // 3rd parameter: ImageList; RichView holds only link to this image list, not
  // a copy of it;
  // 4th parameter: index of paragraph style (-1 to continue paragraph)
