Nashorn can use JavaFX canvas to draw images like it is in HTML5.

The possibility of testing this should be added to Nashorn WS.
2 example tests were made (drawing algorithms were taken from Google Experiments).
Later more tests will be added.

To run JavaFX Nashorn tests one should go to $NASHORN_WS/make directory and type
$ANT_HOME/bin/ant testjfx

The host where the tests are run should have a display connected.
