Detailed Description

Iterator needs to allow the user to avoid full 3D comparison in two cases:

(1) Where (*current)->deepest < target[2], where the occluder is unambiguously in front of the target point.

(2) Where (*current)->shallowest > target[2], where the occluder is unambiguously in back of the target point.

In addition, when used by OptimizedFindOccludee, Iterator should stop iterating as soon as it has an occludee candidate and (*current)->shallowest > candidate[2], because at that point forward no new occluder could possibly be a better occludee.
