I'm still very new to blender, and haven't quite gotten on top of the 
code, so a few more questions if I may...

Objects seem to have dependency information, object->parent and such, 
(with future reference to the dependency graph I hear is being worked 
on). So to what extent does blender depend on this being intact, or can 
it be rebuilt if if I manage to just send the raw object->data (etc), 
and append them to the list of objects ( using BLI_addtail(...), yes?)

Additionally, could you give me a few more tips as to the sizes of these 
arrays, which I assume will be stored as part of the Object struct?

Thanks again
