Original issue's description:
> Try backing SkPicture with SkRecord in Chromium.
> 
> This is our first attempt, mostly to feel this out.  Performance and
> correctness problems are both possible.  Please revert this if a benchmark even
> smells funny.
> 
> That said, we've been working on this a while, are pretty confident it's good
> stuff, and have had Skia's internal testing entirely switched over for a week.
> Parts of Chromium that serialize and deserialize SkPictures are already
> switched over.  This CL finishes things off by switching the default
> recorded-from-scratch SkPicture to use SkRecord too.
