AAT::Lookup has no other way to detect whether it is returned from a real and sanitized font data or from a null pool, this checks if the table has been recognized valid by sanitizer by checking table's major version which is zero if returned from a null pool and non-zero if is from a sanitized font data, it is expected the other calls of the table (unlikely to have more calls however) also do a similar version check before calling the lookups used on the table. |
