Austin Eng 38534b6e74 D3D12: Only set the root signature when bind groups are applied 
Dawn only reapplies bind groups that have changed on the layout
since the last draw. However, the D3D12 backend was always resetting
the root signature state upon switching pipelines. This led to a
bug where the root signature could be changed and dirtied without
reapplying the dirty bind groups.

Moving application of the root signature state to the same loop
that applies bind groups helps ensure the state stays in sync.

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
