Detailed Description

Sparse Voxel Octree: (compressed) 3D Analog of a GBuffer.

The algorithm operates in three passes:

prepare (initialize data structures)
render voxel fragments (Surface::renderIntoSVO)
complete (build the tree)

The octree always fills a cube (it is sparse, so very little space is lost if the aspect ratio is more extreme)
