tools/pdbgen/pdb/progress.pdb applied slightly modified patch from 

2006-02-20  Sven Neumann  <sven@gimp.org>

	* tools/pdbgen/pdb/progress.pdb
	* libgimp/gimpprogress.[ch]: applied slightly modified patch from
	Stephane Chauveau.  Wraps the gimp_progress_update() PDB call so
	that redundant progress updates are suppressed in libgimp.  This
	gives a noticeable speedup for all plug-ins that update the
	progress too often (bug #331470).

	* libgimp/gimpprogress_pdb.[ch]: regenerated.
