1. Update WR (pixel snapping improvements). …

   This includes a WR update that improves pixel snapping. Specifically,
   the non-transform shader now snaps to device pixels in world space,
   rather than local space.
   
   This makes 31 new tests pass, and adds 4 new failures.
   
   Of the new failures:
    - The three background size tests appear to be an OSMesa accuracy
      issue. Near the bottom of the image, a small number of pixels
      are different from the reference by a value of 1.0 / 255.0. I've
      confirmed on 3 real GPUs and also on llvmpipe that the tests
      match on those devices. This would be a good case for fuzzy test
      support in WPT.
    - The other failing test appears to have unreasonable accuracy
      requirements as it also fails on Gecko and Chromium in the same
      way that the test now fails on WR.
