Sorry to disagree again, but no, It can be done with a good uniform scaling of
the object so it keeps the curent scale of the objects. This should be quite
easy to implement.
something like this is in my mind..

translate -1*MinExtent
//that should center the object with one corner on <0,0,0>

Then there should be a scaling, something like:
scale 1/(MaxExtent-MinExtent)
...
in my mind the tree will keep it's scale in sizes, but be downscaled to fit...
perhaps I'm to tired to think straight, but then, what good is straight?
(Go chaos, go)
