	* app/core/gimpimage-convert-data.h
	* app/core/gimpimage-convert.c
	* app/core/gimpimage-convert.h
	* tools/pdbgen/pdb/convert.pdb: Applied slightly modified patch
	from David Gowers allowing a custom dither matrix to be used when
	converting images to indexed mode.  Fixes bug #136604.

	* app/pdb/convert_cmds.c
	* libgimp/gimpconvert_pdb.h
	* libgimp/gimpconvert_pdb.c: Regenerated.

	* app/tools/gimpselectiontool.c: N_() should have been _().
