Servo improves WebGPU support, gets new browser UI

Servo, the Rust browser engine originally developed by Mozilla, has posted an update about the project’s progress over the past month, and there’s a lot of good stuff in there. While our WebGPU support is still very much experimental (–pref dom.webgpu.enabled), it now passes over 5000 more tests in the Conformance Test Suite, after an upgrade from wgpu 0.6 (2020) to 0.16 (2023) and the addition of GPUSupportedFeatures. A few WebGPU demos now run too, notably those that don’t require changing the width or height on the fly, such as the Conway’s Game of Life built in Your first WebGPU app. On the CSS front, floats and ‘white-space: nowrap’ were previously only supported in our legacy layout engine (–legacy-layout), but now they are supported again, and better than ever before! Floats in particular are one of the trickiest parts of CSS2, and our legacy version had many bugs that were essentially unfixable due to the legacy layout architecture. On top of this and other improvements, Servo’s reference browser now also comes with a new user interface, and it comes with a location bar! Keep in mind this is not supposed to be a full-fledged user interface comparable with Chrome or Firefox, so don’t expect the world as a user.
