	* app/core/gimpgradient.[ch]: removed the "last_visited" field
	from GimpGradient. Instead added the new function
	gimp_gradient_get_color_at_segment() that allows the caller to do
	the same optimization.

	* app/actions/gradient-editor-commands.c
	* app/core/gimpdrawable-blend.c
	* app/core/gimppalette-import.c
	* app/paint/gimppaintoptions.c
	* app/widgets/gimpgradienteditor.c
	* app/widgets/gimpgradientselect.c
	* app/widgets/gimpviewrenderergradient.c: changed accordingly.

	* app/pdb/gradient_cmds.c
	* app/pdb/gradients_cmds.c: regenerated.
