The fpnge-derived DEFLATE literal encoder in src/exr_fpnge.c (the constrained
Huffman-table construction and code-length encoding) and its PSHUFB per-byte
Huffman-table lookup kernel in src/exr_simd_x86.c are derived from fpnge and
have been modified (ported from C++ intrinsics to pure C11, reduced to a
generic literal-only DEFLATE encoder, and the bit-packing reimplemented).

    fpng's low-level DEFLATE/Huffman routines are themselves derived from the

    Alistair Moffat and Jyrki Katajainen (November 1996, public domain).
