eaf232cad9 single tree (by default) 
now that build is nlogn (it should be worth to the tree of trees)

7afffd2950 Just another experimental stuff to optimize the expected number of BB test on bvh trees 
*tree pushdowns after the pushsups :P (its still not local optimum)

a6b328b825 *Moved rtbuild to bf_render_raytrace 
*Added vbvh - Just a experimental tree type :)
Variable Way BVH - there is no hardcoded number of childs per each Tree Node
 - idea is to optimize a tree to reduced the expected number of BB tests even after applying SAH (for that an hardcoded n-way is not enough)
 - for now childs are stored on a linked list
