GLES: allow clients to pass an explicit EGLDisplay.

Add a new "display" parameter to RequestAdapterOptionsGetGLProc. This allows clients to explicitly specify the display on which to create contexts. This is more robust than depending on the correct display to be current (or falling back to default) when creating a context.

If no RequestAdapterOptionsGetGLProc or no display is passed, use the old logic. This allows Dawn standalone to work without change.

This requires storing the EGLDisplay in opengl::PhysicalDevice, so
that it can be used for the context subsequently created for each WGPUDevice.

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, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
