Methods:

• public abstract bool drag_data_delete (TreePath path)
  Asks the TreeDragSource to delete the row at path, because it was moved somewhere else via drag-and-drop. Returns false if the deletion fails because path no longer exists, or for some model-specific reason. Should robustly handle a path no longer found in the model!
• public abstract bool drag_data_get (TreePath path, SelectionData selection_data)
  Asks the TreeDragSource to fill in selection_data with a representation of the row at path. selection_data->target gives the required type of the data. Should robustly handle a path no longer found in the model!
• public abstract bool row_draggable (TreePath path)
  Asks the TreeDragSource whether a particular row can be used as the source of a DND operation. If the source doesn't implement this interface, the row is assumed draggable.
