	* app/core/gimpimage-convert.[ch]:
	RGB->Indexed quantizer version 3.0 (the rest of the commit started
	a year ago -- whoops).  Divide colours within CIE L*a*b* space using
	CPercep module (cpercep.[ch]), colour-match and dither likewise,
	change the underlying box selection criteria and division point
	logic, bump luminance precision upwards, etc. etc.

	* app/core/cpercep.[ch] (new files): utility module used by
	quantizer for quantifying perceptual colour distances

	* app/core/gimpimage-convert-data.h (new file): move the big
	static data arrays out of gimpimage-convert.c

	* app/core/gimpimage-convert-fsdither.h: static-ify data

	* app/core/Makefile.am: add cpercep.[ch] and gimpimage-convert-data.h
