attached is a patch that implements that. With it applied I get:

when running the program (with all #if 0 changed to #if 1). So there
still is an Image and a TextureObjChunk in the renderThread that I don't
think should be there (the remaining 4 objects are part of the default
material so that is ok).

well, actually it is the other way around, the parent pointer from Image
to TextureObjChunk is causing the problem, because it gets synced over,
but in the destination aspect the TexObjChunk does not exist (since it
was createLocal() ).
