the operators from that library.
    *   Add `CompositeTensor` base class.
    *   Malformed gif images could result in an access out of bounds in the
        color palette of the frame. This has been fixed now
    *   Add templates and interfaces for creating lookup tables
    *   `Tensor::UnsafeCopyFromInternal` deprecated in favor
        `Tensor::BitcastFrom`.

//           can be null. The names used for function inputs are normalized
//           names of the operations (usually placeholders) pointed to by
//           `inputs`. These operation names should start with a letter.
//           Normalization will convert all letters to lowercase and
//           non-alphanumeric characters to '_' to make resulting names match
//           the "[a-z][a-z0-9_]*" pattern for operation argument names.
