I notice that vertical_layout example, the nodes don't have embeddedWidget()
When I call setOrientation on an existing scene containing nodes that do have embedded widgets I get a crash
I believe this may be because the during the change of orientation, the scene has been cleared, and a onModelReset() is called, then the QWidgets have been deleted but their pointers are not reset, and are used to determine the new size.
When I ensure I have a scene with no embedded widgets, no crash, and the nodes reorient themselves correctly.
However, in truth, if the overall orientation of the scene has changed, shouldn't the X,Y coordinates be swapped too?
