Changes the internal BindingInfo structure and any references to it. The BindGroupLayoutEntry information is normalized when converting it into the internal representation, but still accepted as either the old or new layout. A "bindingType" member is added to the BindingInfo that's not present in the BindGroupLayoutEntry itself to indicate which of buffer, sampler, texture, or storageTexture is populated. This proves useful for a myriad of switch statements in the various backends.

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
