	* app/core/gimpimage.c: use GIMP_STOCK_IMAGE as default_stock_id.

	* app/widgets/gimppreviewrendererimage.[ch]: use GimpChannelType
	to specify the channel to render and convert it to the pixel index
	using gimp_image_get_component_index() when needed. Use the new
	red, green, blue, gray and alpha icons when layer_previews is
	FALSE.

	* app/widgets/gimpcomponenteditor.c: changed accordingly.
