ValidateOrSetAttachmentSize() was asserting that textureSize.width >> attachment->GetBaseMipLevel() is nonzero. This is not true for rectangular textures, where the smaller dimension may hit the lower bound and must be be clamped at 1. Fixed by calling GetMipLevelVirtualSize() which performs the clamp. Added a test which exercises rectangular mipmapped textures as color attachments. This required a few fixes to the test harness, which had the same bug as that fixed in the code (assumes (width >> size) > 0).

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
.
- The
- 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
