solve issue 1640 (CartoonEdgeFilter failing to override read() and write()) (#1647)

* solve issue 1640 (CartoonEdgeFilter failing to override read() and
write())

- remove unused import and extra empty lines from CartoonEdgeFilter
- add test case for CartoonEdgeFilter save and load

* fix for Desktop Asset Manager creation while run test case for
CartoonEdgeFilter

* add javadoc
