This patch adds the basic supports of both read-only and write-only storage textures on Metal with several simple end2end tests that use read-only or write-only storage textures in every shader stage. Here are the follow-ups after this patch: 1. test all the texture formats that can be used as both read-only and write-only storage textures. 2. support using a texture with multiple different binding types in one rendering or compute encoders. 3. test image2DArray, imageCube and imageCubeArray.

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
