CefBrowserHostDragSourceSystemDragEnded Method

Call this method when the drag operation started by a CefRenderHandler::StartDragging call has completed. This method may be called immediately without first calling DragSourceEndedAt to cancel a drag operation. If the web view is both the drag source and the drag target then all DragTarget* methods should be called before DragSource* mthods. This method is only used when window rendering is disabled.
