	* app/widgets/widgets-enums.h
	* app/widgets/gimppreviewrenderer.[ch]: New function
	gimp_preview_renderer_set_border_type that takes an enum instead
	of an color to set the color of the border.

	* app/widgets/gimpcellrendererviewable.c: check for the
	current border_type and change it to black when it is white and
	the cell is unselected. This should be solved in a better way
	later.

	Fixes bug #135023.

	* app/widgets/gimplayertreeview.c
	* app/widgets/gimpcontainergridview.c: changed to use the new
	function.
