Changed is an overridden method in TRasterImage used to perform actions needed when property values in the class instance have been updated. No actions are performed when BeginUpdate has been called and a corresponding EndUpdate has not occurred.
Changed ensures that the SaveStream used in the shared image is freed.
Changed calls the inherited method in TGraphic to set the value for the Modified property and signal the OnChange event handler (when assigned).
