// A very simple implementation where we assume that there's only one window and that it's a
// QQuickWindow. Thus the id parameter is irrelevant.
//
// Idea: Make the id contain the objectName of the QQuickWindow once we care about a multi-display
//       compositor?
//       Strictly speaking that could be the actual QWindow::winId(), but that's mostly a
//       meaningless arbitrary number.
