Castle Game Engine and view3dscene do generate level_changed on 1st
display. When implementing, I thought that it is sensible: the display
changes from "nothing" to "that child node", so I was thinking just as
But I have not tested other X3D browsers about this. A confirmation
would be welcome. Maybe my old LOD testcase may be adapted?
