69: Swapchain resize r=kvark a=kvark Based on #67 Here are the steps (as outlined on Gitter) that this PR follows: 1. create a dummy frame in the swapchain (`SwapChain::outdated`). We return it when we aren't able to acquire a real frame. No synchronization is done atm, but shouldn't be anything critical there. 2. handle the errors on acquire and present, use the dummy frame where needed. Presentation errors are just ignored, while acquiring errors are forcing the dummy frame. The idea is that the user would know about a swapchain resize from some kind of event loop / WSI, and thus they'd know when they should actually re-create it. 3. associate surface with a swapchain. We merge the IDs since there can't be multiple swapchains on the same surface in the near future. Merging simplifies a lot of things in the implementation, but this is to be revised for sure once we get a better look on the browser integration. 4. when the swapchain is re-created, consume the old one associated with a surface.

WebGPU
This is an experimental WebGPU implementation as a native static library. It's written in Rust and is based on gfx-hal and satellite libraries. The corresponding WebIDL specification can be found at gpuweb project.
The implementation consists of the following parts:
wgpu-native- the native implementation of WebGPU as a C API librarywgpu-bindings- automatic generator of actual C headerswgpu-remote- remoting layer to work with WebGPU across the process boundarywgpu-rs- idiomatic Rust wrapper of the native library
Example
To run an example, simply cd to the examples or gfx-examples directory, then use cargo run with --features {backend} to specify the backend (where {backend} is either vulkan, dx12, dx11 or metal). For example:
# Clone the wgpu repository
git clone https://github.com/gfx-rs/wgpu
# Change directory to `examples`
cd wgpu/examples
# Vulkan (Linux/Windows)
cargo run --bin hello_triangle --features vulkan
# Metal (macOS/iOS)
cargo run --bin hello_triangle --features metal
# DirectX12 (Windows)
cargo run --bin hello_triangle --features dx12
cd ../gfx-examples
# Vulkan (Linux/Windows)
cargo run --bin cube --features vulkan
# Metal (macOS/iOS)
cargo run --bin cube --features metal
# DirectX12 (Windows)
cargo run --bin cube --features dx12
These examples assume that necessary dependencies for the graphics backend are already installed. For more information about installation and usage, refer to the Getting Started guide.
