pfdLoadFile() returns a pfNode*, which is a higher level object than a
pfGeoSet. If you want to get down to geoset level and change geoset attributes,
you'll have to traverse the graph returned from pfdLoadFile(), all the way down
to the geosets. Right now you are trying to call pfGSetHlight() with a pfGroup
or a pfGeode as an argument. I suppose that performer doesn't like it.
