/**
* Action that invokes {@link Chart2D#setUseAntialiasing(boolean)}
* upon selection by the triggering {@link AbstractButton}.
*
* Also this Action
will track the state {@link Chart2D#isUseAntialiasing()}
* as a listener of the chart and inform all listeners of this action for the event {@link LayoutFactory.PropertyChangeCheckBoxMenuItem#PROPERTY_SELECTED}
* with the new state.
* To listen to this action just have a look at the usage of {@link LayoutFactory.SelectionPropertyAdaptSupport}.
*
*
Caution
This implementation only works if assigned to a trigger that
* descends from {@link AbstractButton} (e.g.
* {@link javax.swing.JCheckBoxMenuItem} or {@link JRadioButtonMenuItem}): It
* assumes that the source instance given to
* {@link #actionPerformed(ActionEvent)} within the action event is of that type
* as the state information (selected) is needed.
