The ::drag-leave signal is emitted on the drop site when the cursor
leaves the widget. A typical reason to connect to this signal is to
undo things done in "drag-motion", e.g. undo highlighting
with gtk_drag_unhighlight().
Likewise, the "drag-leave" signal is also emitted before the
::drag-drop signal, for instance to allow cleaning up of a preview item
created in the "drag-motion" signal handler.
