- Removed the `always_vertex` parameter from `build_surface_camera` to streamline depth sampling for cutouts and ensure consistent behavior across depth plane and panorama. - Updated depth sampling logic to ensure that all free boundary points, including the original frame of the depth plane, use neighboring face depth instead of their own texture sampling. - Adjusted the depth mask deletion process to operate on faces rather than points, eliminating the need for additional cleanup of dangling edges. - Ensured that the cutout rules are consistently applied across all relevant nodes, removing exceptions and simplifying the logic. - Updated tests to verify the new behavior, ensuring that cutout points follow the depth of adjacent faces and that the original frame maintains its depth sampling. - Refactored geometry handling in multiple depth-related nodes to improve clarity and maintainability.
