Description
We should expose a fast helper to determine whether a chunk could possibly be visible from a certain point given a certain maximum geometric displacement, to aid in CPU culling of terrain geometry. The cache manager should take advantage of this.

Research direction
Start by locating the chunk and cache manager entry points, then trace how terrain visibility and geometric displacement are currently represented. Define and expose the horizon-culling helper, have the cache manager use it for CPU culling, and verify that chunks which could not be visible are excluded without removing potentially visible geometry.
