When wgpu::VertexStepMode::VertexBufferNotUsed enum that must
be set to empty vertex buffer slots was introduced its value
was temporarily set to zero to pass some CTS tests by making
the use of zero-initialization without any change in Blink.
We applied a patch to Blink to explicitly set
wgpu::VertexStepMode::VertexBufferNotUsed to empty vertex
buffer slots so we can set the enum value to non-zero.
("Undefined") Zero enum value should be used as the
default as specified in JS" so the APIs match more closely.
The default vertex step mode in VertexBufferLayout is
"vertex" then wgpu::VertexStepMode::VertexBufferNotUsed enum
value shouldn't be zero.

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
- Tint is a compiler for the WebGPU Shader Language (WGSL).
