Pull Request Overview
This PR refactors the SSAOPass visibility caching system to improve performance by replacing the Map-based cache with an array that only stores objects whose visibility is actually modified. The change eliminates the need to traverse all scene objects during restoration and reduces memory overhead.
- Replaces Map-based visibility cache with array for better performance
- Only caches objects that have their visibility modified (Points, Line, Line2 objects)
- Optimizes restoration by iterating only cached objects instead of entire scene

This PR refactors the SSAOPass class in
examples/jsm/postprocessing/SSAOPass.jsto improve how object visibility is cached and restored during the SSAO pass. It improves performance and clarity by only tracking objects whose visibility is actually modified.We can reduce the SSAO pass render time by nearly 40-50%.
