It was my goal to create benchmarks that could measure all of the use cases that we have identified. I think single subsets, translating, and scaling are the important ones. It might be a good idea to discuss the document in greater detail as well. I just wanted to share this to aid the discussion. https://docs.google.com/a/google.com/document/d/1OxW96GDMAlw6dnzNXmiNX-F9oDBBlGXzSsgd0DMIkbI/edit?usp=sharing BUG=skia: Review URL: https://codereview.chromium.org/1160953002
