[Bf-funboard] Limits on size

I'm working on a Python solution for the problem, actually, but it is still a 
hack and a work-around.  Given how far Blender has come in the last few 
years, it is a step I am happy to make.  But the reason for such a fix is 
more fundamental....

I need to have one scene instead of a composition of scaled scenes because the 
set is used in a game scenario.  As Blender's use of Verse improves, it will 
enable multiple people to run Blender at the same time.  In such a scenario, 
having multiple scales composited together amounts to a shell game, which is 
unnecessary when lifting the limits on the ranges would be easier.  Or so it 
seems.

I'm using Python in the meantime....
