The idea is that we already have a GimpProcedure object in libgimp which has name, help, blurb, arguments, return values and everything, so we really don't need a parallel API to query PDB procedures for their properties. - make run() a virtual function of GimpProcedure - move GIMP_PDB_ERROR to GimpPDB - GimpPDBProcedure is a trivial subblass which populates GimpProcedure's members by querying the PDB. - make "plug-in", "procedure-type" and "name" construct-only properties of GimpProcedure. This is all work in progress.
