// [OP-1586] make sure that the view never becomes parent less otherwise a rendering bug happens
// in osgearth QML views (not all kind of scenes are affected but those containing terrain are)
// Making the view parent less will destroy the OpenGL context used by the QQuickFramebufferObject used OSGViewport
// A new OpenGL context will be created but for some reason, osgearth does not switch to it gracefully.
// Enabling the stats overlay (by pressing the 's' key in the view) will restore proper rendering (?).
// Note : avoiding to make the view parent less is a workaround... the real cause of the rendering bug needs to be
// understood and fixed (the same workaround is also need in unsplit and unsplitAll)
// Important : the changes also apparently make splitting and un-splitting more reactive and less jumpy!
// Give our view to the new left or top SplitterOrView.
