Using Scene Builder Kit inside an SWT application, I noticed that the image
passed to Dragboard.setDragView() is not correctly rendered.

Use the attached Eclipse project to reproduce the pb:

1) Unzip TestDragAndDropSWT.zip
2) Setup references to jfxswt.jar and swt.jar
3) Start the sample
4) Drag from the blue rectangle
    => duke.png has been passed to DragBoard.setDragView()
    => but it is not visible during dnd : only a white square is displayed : BUG
