	* app/bezier_select.c: add the new args to gimp-paintbrush PDB
	    calls.

	* app/blend.c
	* app/bucket_fill.c
	* app/invert.c: check return from procedural_db_run_proc() rather
	    than dereferencing NULL.

	* app/paintbrush.c: plumb the non-gui fade_out option into the
	    functions that actually do the work, rather than using
	    an uninitialised value.

	* app/procedural_db.c: better error messages on PDB typecheck fail
	    in procedural_db_run_proc.  Also now valid to
	    procedural_db_destroy_args() on a NULL pointer.
	* app/procedural_db.h: pdb_type_name() function added, plus
	    comment urging people to keep the enum and strings in step.

	* tools/pdbgen/README: added paragraph on how to run pdbgen.pl

	* tools/pdbgen/pdb/tools.pdb: fade_out parameter is valid to be 0
	* app/tools_cmds.c: new version of generated file
