Added an extra face sorting step so we can draw faces in front-to-back order: - Nodes are traversed front-to-back, leafs are sorted back-to-front
- Leaf faces are collected back-to-front to ensure faces shared between leaves are drawn in the correct order
- Faces to be drawn are then sorted front-to-back and drawn in that order
- This obsoletes the need for any kind of depth calculations, and makes the primitive buffer cutoff work as intended
