  * The symbols are indexed and the index is incremented for each symbol added starting from 1.
  * When a SymbolListWidget is assigned to the SymbolLibrary each of the symbols is added to
  * the SymbolListWidget which will create a QListWidgetItem which is assigned the QIcon that
  * is generated from the QPainterPath associated with the index.
