// dear imgui: Renderer for WebGPU
// This needs to be used along with a Platform Binding (e.g. GLFW)
// (Please note that WebGPU is currently experimental, will not run on non-beta browsers, and may break.)
// This needs to be used along with a Platform Binding (e.g. GLFW, SDL2, SDL3)
// (Please note that WebGPU is a recent API, may not be supported by all browser, and its ecosystem is generally a mess)
// Important note to dawn and/or wgpu users: when targeting native platforms (i.e. NOT emscripten),
// one of IMGUI_IMPL_WEBGPU_BACKEND_DAWN or IMGUI_IMPL_WEBGPU_BACKEND_WGPU must be provided.
// When targeting native platforms:
// - One of IMGUI_IMPL_WEBGPU_BACKEND_DAWN or IMGUI_IMPL_WEBGPU_BACKEND_WGPU *must* be provided.
// When targeting Emscripten:
// - We now defaults to IMGUI_IMPL_WEBGPU_BACKEND_DAWN is Emscripten version is 4.0.10+, which correspond to using Emscripten '--use-port=emdawnwebgpu'.
// - We can still define IMGUI_IMPL_WEBGPU_BACKEND_WGPU to use Emscripten '-s USE_WEBGPU=1' which is marked as obsolete by Emscripten.
// Add #define to your imconfig.h file, or as a compilation flag in your build system.
// This requirement will be removed once WebGPU stabilizes and backends converge on a unified interface.
