This patch adds the support of the optional feature "bgra8unorm-storage" on D3D12 when the platform allows using DXGI_FORMAT_B8G8R8A8_UNORM as UAVs. According to D3D12 documents, enabling the flag D3D12_RESOURCE_FLAG_ALLOW_UNORDERED_ACCESS when creating textures requires "either the texture format must support unordered access capabilities at the current feature level. Or, when the format is a typeless format, a format within the same typeless group must support unordered access capabilities at the current feature level".

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.
