Glenn Watson cbe7f09f81 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.		2017-02-13 23:46:28 +01:00
