Ben Clayton 06b827ee92 dawn_node: Only rebuild CTS if something has changed
https://github.com/gpuweb/cts/pull/788 significantly improves the performance of incremental builds, but it can still take around 2 seconds to do that incremental build.

Have the run-cts tool scan the CTS source tree for the most recent modification, and only rebuild if the timestamp is more recent than the last build time.

Significantly reduces startup overhead of the tool.

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.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • 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
