[Bf-committers] Default for Raytracer Instancing

[Randall Rickert]

When I read the post about instancing being off by default, I was in the
middle of a big project with raytracing and lots of instancing. I can
turn on instancing to save some rendering time, right?

Wrong! Turning on instancing gave me longer render times, and it also
made a small but visible difference in final gather. This is just the
first file I tried rendering with instancing turned on, and I have not
tried with other projects yet. Definitely not a large enough sampling to
draw broad conclusions, but maybe turning it on by default is not such a
simple answer after all.
