Mathias Agopian 38de58007c checkpoint: ground work for calculating binary light trees ...

computeLightTree() takes a list of light as
a bitfield and produces a depth-first 
binary tree array that can be used to efficiently
check which lights volumes contain a given z
coordinate in screen space.

Currently computeLightTree() produces the array
locally on the stack, which isn’t useful, but
before we can make use of it, a lot of other
things have to happen.
