## Library & Tooling Updates

### [wgpu-rs]

wgpu-rs is a WebGPU implementation and API in Rust.

- "wgpu-core"-0.7.1 was published with fixes
- API updated for blending states, cull faces, vertex formats.
- zero-initialization of buffers upon use.
- validation of texture bindings, index formats for strip topologies.
- binding tracker was rewritten with test-ability in mind, bugs fixed.
- the player learned to resize the window properly. API traces can now
be replayed on Linux even when swapchain recreation events are present.
- SPIRV-Cross was made optional, which was useful for Deno in order to
work around the linking conflict with "rusty_v8".

### [gfx-rs]

gfx-rs is a portable low-level graphics abstraction layer.

- API got `PhysicalDeviceProperties` containing limits and properties of
physical devices that are not opt-in.
- SPIRV-Cross dependency was made optional, while Naga is required.
- Vulkan backend learned to target Vulkan 1.1 and 1.2 internally.
- DX12 understood more limits.
- GL backend fixed WebGL initialization and EGL library discovery.

### [naga]

naga is the shader translation library/tool.

- versions 0.3.1 and 0.3.2 were published with fixes
- API: function calls turned into statements, image queries and stores,
understanding of push constants.
- validation: type validation was re-written and improved, new control flow
analysis was added to check for uniformity requirements. In addition,
this step now collects the image-sampler pairs used by the module.
- backends: lots of fixes and filling of the gaps
- infrastructure: `convert` example was removed in favor of the default
binary target. The native shaders (produced by the snapshot tests)
got validated on CI using platform tools.
