addec const qualifiers to GimpRGB parameters.

Browse Source 
2007-12-28  Sven Neumann  <sven@gimp.org>

	* libgimpwidgets/gimpcairo-utils.[ch]: addec const qualifiers to
	GimpRGB parameters.

	* app/widgets/gimprender.[ch]: removed global variables for
	checkerboard colors and introduced functions to get the
	checkerboard colors as pointers to GimpRGB structs.

	* app/actions/view-actions.c
	* app/display/gimpdisplayshell-appearance.c
	* app/widgets/gimpviewrenderer.c
	* app/widgets/gimpcolormapeditor.c: changed accordingly.
