// The JavaFX plot is inside an FXCanvas.
// The FXCanvas establishes an SWT DropTarget
// to forward drops from SWT to the hosted JavaFX scene.
//
// Issues:
// The FXCanvas only reliably forwards standard transfers
// (string, ..), and not custom data types.
// SWT generally doesn't allow multiple drop targets.
//
// Option 1)
// Use the JavaFX drop API on the plot, and parse the received strings.
// -> Don't want to parse possibly arbitrary strings.
//
// Option 2)
// Change the ControlSystemDropTarget to use
// getSite().getService(IDragAndDropService.class).addMergedDropTarget(..)
// https://bugs.eclipse.org/bugs/show_bug.cgi?id=162192

// would only work in RCP, not plain SWT.
// Who then receives the drop events would depend on the order
// in which drop targets are added and which transfers they use.
//
// Option 3)

// the FXCanva's DropTarget via
// control.getData(DND.DROP_TARGET_KEY);
