HLSL-IR: Fix texture Sample and SampleLevel return type on depth textures HLSL's texture Sample and SampleLevel functions return a vector, and we must swizzle the first component when sampling a depth texture. Fixes 6 failing e2e tests.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the 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.h version that Dawn implements.
- A C++ wrapper for the webgpu.h.
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.
