Not sure what I had in mind with the class method copy() in libgimp GimpLayer. The core duplicate code already takes care of returning an object of the right type. Also the GimpTextLayer implementation was not a perfect copy (only text, font and font size were copied). Now it is because, again, core has all the duplication code necessary. Finally this makes this function visible to PDB, hence Script-Fu, again.
