This makes all backends register the default queue at device initialization time, so that the same queue is returned by each call to GetDefaultQueue. All usages of CreateQueue are replaced by GetDefaultQueue except a couple ones that could use the queue initialized by DawnTest::SetUp. A deprecation warning mechanism is added so that users of Dawn can now that they should upgrade their usage of the API. It also comes with a backdoor so we can test that they are emitted. New DeprecatedAPITests are added that will contain tests for deprecated APIs, and will also check that deprecation warnings are produced. The special casing of GetDefaultQueue in the wire will be done in a follow-up CL to ease the review. It happens to work through the regular wire mechanisms at the moment but returns a different object on each GetDefaultQueue call.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs:
- D3D12 on Windows 10
- Metal on macOS and iOS
- Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
- OpenGL as best effort where available
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
