When we are copying data, we need to offset "rowsPerImage" rows for each depth slice, even though this is a partial copy whose copy height is less than rowsPerImage. In addition, when we copy the original data into expected buffer for comparison, we don't pack data for T2B copy and T2T copy. We don't remove paddings during copy. So I renames PackTextureData to CopyTextureData. For B2T copy, we do pack data. Right now we name it CopyXXXX and we pack the data during some copies, it is understandable. But if we name it PackXXXX but don't pack data sometimes, it is weird. In addition, for B2T copy, we pack the data, so I shorten the buffer size we allocated for comparison. This change also renames "slice" to "layer" if it includes multiple depth slices and actually means a layer, but keep slice as slice if it means an array layer or a depth slice for different cases.

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.hversion 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
