I know, just wanted to drive home a point ;)
And then I even forgot to stress that also the fact that you better not 
change the scene after you started rendering also points to the fact 
that a camera should be handled slightly different from the scene 
generation. Passing it as a read only parameter to the camera function 
would be an clear solution.
