In 0.4 graph traversal is done much more flexible, ie. you have various 
kinds of traversals. This is done like that because first the design is 
cleaner and easier to enhance and second it can be better optimised on 
multi processor systems. BTW you cannot easily perform the bbox update 
while traversing upwards because the app might change the graph 
afterwards (before rendering the next frame) - or do you think of sth 
different here?

And I dare to say that the 3DKit is not aimed at games, in games you 
need a highly tuned, specific implementation, so the 3DKit is more 
designed to serve visualisation, modelling and research needs.
