// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2025-02-26: Recreate image bind groups during render. (#8426, #8046, #7765, #8027) + Update for latest webgpu-native changes.
// 2024-10-14: Update Dawn support for change of string usages. (#8082, #8083)
// 2024-10-07: Expose selected render state in ImGui_ImplWGPU_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
// 2024-10-07: Changed default texture sampler to Clamp instead of Repeat/Wrap.
