comparison rdf/RDFFeatureWriter.cpp @ 500:83eae5239db6

* Permit viewing (though not editing) colour 3d plot layer data in
  the spreadsheet data viewer dialog
* Add somewhat simplistic RDF export for layers
* Fix display of peak frequencies in spectrum layer
* Fix (I hope) sizing of plugin parameter dialog
