- Ensure the yadif .metal compiles when targeting any Metal runtime version - Use some preprocessor awkwardness to ensure Core Video's Metal-specific functionality is exposed regardless of our deployment target (this works around what seems to be an SDK header bug, filed as FB9816002) - Ensure all direct references to Metal functions and classes are gated behind runtime version checks (this satisfies clang's deployment-target violation warnings provided by -Wunguarded-availability).
