/**
* Illustrates how to cause all elements under the cursor in a WorldWindow to be reported in {@link
* SelectEvent}s. This prints all elements under the cursor to the console in response to a HOVER
* SelectEvent.
*
* In order to enable deep picking, any batch picking for the desired elements must be disabled and the
* SceneController's deep picking property must be enabled. See {@link gov.nasa.worldwind.SceneController#setDeepPickEnabled(boolean)}.
