Merge tomhudson and mtklein SkPaint shrinking approaches.
I think this is cherry picking the best parts of both our CLs. We've got dirty bit tracking from Tom's, picture format stability from Mike's, etc. Paints are typically 1/3 their original size when flattened in the dictionary.
bench_record on my desktop looks promising. Generally, looks faster. (Best in monospace.)
