    ops: add hashes of reference composition for some ops
    
    This is start of work integrate testing with the automatic operation gallery,
    making it less neccesary to deal with automake and GEGL XML for having
    regression tests in place. Using nice and short MD5 hashes since we're using it
    as a checksum not to cryptographicly verify code or something we need to trust.
