Bryan Bernhart 303a3daf0d D3D12: Decouple descriptor heap allocations.
Allows bindgroups to be populated by heap type. Previously, failing to
populate one type of GPU descriptor heap required both GPU heaps
to be switched out. This resulted in extra copies and heap allocations
should only one heap type overflow.

This change also simplifies GPU descriptor heap management:
- Allocator no longer needs to operate on both heaps.
- Sub-allocation tracking can be moved into handles.

A follow-up change will remove duplicated sampler heap allocations.

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
