2006-09-26  Sven Neumann  <sven@gimp.org>

	* modules/Makefile.am
	* modules/colorsel_cmyk_lcms.c: new CMYK color-selector that
uses
	littleCMS for the RGB <-> CMYK conversion. This is built instead
	of the standard CMYK color-selector if lcms is available.

	* libgimpwidgets/gimpcolornotebook.c
	* libgimpwidgets/gimpcolorselection.[ch]
	* libgimpwidgets/gimpcolorselector.[ch]
	* libgimpwidgets/gimpwidgets.def: added API to set the color
	management configuration on color selectors.

	* libgimpwidgets/gimpwidgetstypes.h: include
	libgimpconfig/gimpconfigtypes.h.

	* app/dialogs/grid-dialog.c
	* app/dialogs/preferences-dialog.c
	* app/widgets/gimpcolordialog.c
	* app/widgets/gimpcoloreditor.c
	* app/widgets/gimpcolorpanel.c
	* app/widgets/gimpgrideditor.[ch]
	* app/widgets/gimppropwidgets.c
	* app/widgets/gimptoolbox-color-area.c: set the color management
	configuration on (hopefully) all color selectors.

	* modules/cdisplay_lcms.c: use a GimpHintBox widget.
