Oh right, forgotten about this. I guess now that the hw stuff is there
we can resurrect this. And with the universal planes support we could
move the "prefer backbuffer rendering" hint to planes even where it
imo belongs (since e.g. fbc is on the plane). Or maybe we don't care
about that level of granularity and just have one per pipe.
