Austin Eng 3120d5ea0d Track and destroy all child objects on wire client destruction 
This is needed so that:
 1. We can support multiple devices in the wire. The device will need
    to know how to destroy its child objects.
 2. The wire needs to be aware of all objects and their in-flight
    callbacks so that it can reject them if the wire is disconnnected.
    A future change will handle this.
 3. Fix leaks of objects on page teardown. When the page is torn down,
    the wire client is destroyed, and we skip calling release() for all
    objects since the object holding the proc table was also destroyed.

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
