Wide Review for WebGPU and WGSL

[AdaRoseCannon]

The GPU for the Web Working Group has made significant progress on first
versions of the WebGPU and WebGPU Shading Language (WGSL)
specifications. The group is now firming up the specifications with a
view to requesting publication as Candidate Recommendations later this
year.

The Working Group would like to invite you to review the latest versions
of the specifications:

• WebGPU: https://www.w3.org/TR/webgpu/
• WGSL: https://www.w3.org/TR/WGSL/

Working drafts are updated on a continuous basis but there should be no
more breaking changes at this stage. Feel free to review dated versions
of the specifications to avoid looking at a moving target.

Brandon prepared an explainer some time ago to lay out a plan for
integrating WebGPU in WebXR [This repo]. If further changes to WebGPU seem
warranted, now would be a good time to raise needs.

The Working Group plans to request publication as Candidate
Recommendations no sooner than 15 October 2022 and welcomes comments
prior to that date, preferably through issues on the group's GitHub
repository:
