+ * @brief The LineOfSightImpl class supports a "single" line with two colors.
+ * The method setPositions() should never be called.
+ * A class instance consists of the following logical elements:
+ * - mainGraphicalObject      (GraphicalObjectPath displaying the main techn. Appearance)
+ * - mainGraphicalObjectText  (displaying the text/name/identifier)
+ * - tacticalAppearance       (displaying the tact. Appearance)
