Makes it clear that the index being reported by these messages is the group index and not the binding number. This was a point of confusion in on the bug. Additionally, adds more information to the error message regarding buffer sizes being too small for the current pipeline. Now includes the pipeline name and buffer size as well as the minimum required size. Also includes a note explaining that uniform buffer bindings must be a multiple of 16. (This recently changed and cause several existing samples to break for non-obvious reasons.) The error message still does not contain the buffer or binding number, which would be helpful. This is because we currently lack a way to look up the binding index from the packed index that this error is generated with.

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, Metal, Vulkan and OpenGL. See per API support for more details.
- 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) that can be used in standalone to convert shaders from and to WGSL.
