// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2026-08-18: Fixed passing non-integer sizes to `wgpuRenderPassEncoderSetViewport() when FramebufferScale is >1.0f. (#9515, #8628)
// 2026-04-23: Added support for standard draw callbacks (in platform_io): DrawCallback_ResetRenderState, DrawCallback_SetSamplerLinear, DrawCallback_SetSamplerNearest. (#9378)
// 2026-03-25: Added support for WGVK native backend via IMGUI_IMPL_WEBGPU_BACKEND_WGVK define, with SPIRV shaders if WGSL is not available. (#9316, #9246, #9257)
// 2026-03-09: Removed support for Emscripten < 4.0.10. (#9281)
