Automatic update from web-platform-tests Full implementation of scale transform render surface trigger The general approach is as follows: * Look for 2D scale transforms, and allocate effect nodes for them (if all goes well, this should have little or no effect on cc layer count or render surfaces) * Upgrade the effect node for a 2D scale transform to a render surface if it doesn't have a backdrop filter in a descendant effect node, and has at least two composited layers under it. Also, in particular this approach: * Relies on implicit compositing of scale transform due to presence of composited descendants Bug: 40084005 Change-Id: If7fff045752f5cf1c09e574a81d181b2a8ac4959 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6299812 Reviewed-by: Xianzhu Wang <wangxianzhu@chromium.org> Commit-Queue: Chris Harrelson <chrishtr@chromium.org> Cr-Commit-Position: refs/heads/main@{#1427258} -- wpt-commits: 8dd63a5942f11650d17b34d716dc4da1ae84bec9 wpt-pr: 51062
