    pipeline: Also look at the compat-name when deserializing the graph
    
    Sometimes, we might want to use a different name for an operation in
    the XML serialization of the graph. Since the XML is created with the
    GeglOperation's "name" key, we would use "compat-name" for the
    internal name of the operation. Therefore, we need to look at the
    "compat-name" when creating the mapping from operation names to
    GeglNodes.
