As I said in http://dbaron.org/log/20130306-compositing-blending , I
think there's a lot less to specify and a lot less to drive towards
interoperability if compositing and blending operations are limited
to things that create stacking contexts.  This limitation would be
present if background-blend-mode and background-composite are
dropped, which I think should be done.
