	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimpviewrendererbuffer.[ch]: added a view renderer
	which knows how to preserve a GimpBuffer's aspect ratio if the
	view's aspect ratio is different.

	* app/widgets/gimpviewrenderer-utils.c
	(gimp_view_renderer_type_from_viewable_type): use it for viewables
	of type GimpBuffer. Fixes bug #152531
