Methods:

• public abstract bool drag_data_received (TreePath dest, SelectionData selection_data)
  Asks the TreeDragDest to insert a row before the path dest, deriving the contents of the row from selection_data. If dest is outside the tree so that inserting before it is impossible, false will be returned. Also, false may be returned if the new row is not created for some model-specific reason. Should robustly handle a dest no longer found in the model!
• public abstract bool row_drop_possible (TreePath dest_path, SelectionData selection_data)
  Determines whether a drop is possible before the given dest_path, at the same depth as dest_path. i.e., can we drop the data in selection_data at that location. dest_path does not have to exist; the return value will almost certainly be false if the parent of dest_path doesn't exist, though.
