I thought about doing it this way, and for average scenes, that would be 
fine.  But we are talking code that used for mega-scenes.  Realocating an 
array on the fly sometimes involves copying the current contents to a new 
memory block, and if the machine is already strapped for RAM...  I suppose 
this only happens once per frame,  and we're only talking a few tens of 
thousands of pointers, though.

I'll look into it some more tonight.
