dropDone

Informs GDK that the drop ended.

Passing false for @success may trigger a drag cancellation animation.

This function is called by the drag source, and should be the last call before dropping the reference to the @drag.

The GdkDrag will only take the first method@Gdk.Drag.drop_done call as effective, if this function is called multiple times, all subsequent calls will be ignored.
