// [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// Missing features or Issues:
// [ ] Platform: Multi-viewport: Minimized windows seems to break mouse wheel events (at least under Windows).
// [ ] Platform: Multi-viewport: ParentViewportID not honored, and so io.ConfigViewportsNoDefaultParent has no effect (minor).
// [ ] Platform: Multi-viewport: Missing ImGuiBackendFlags_HasParentViewport support. The viewport->ParentViewportID field is ignored, and therefore io.ConfigViewportsNoDefaultParent has no effect either.
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2025-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2025-09-24: Skip using the SDL_GetGlobalMouseState() state when one of our window is hovered, as the SDL_MOUSEMOTION data is reliable. Fix macOS notch mouse coordinates issue in fullscreen mode + better perf on X11. (#7919, #7786)
// 2025-09-18: Call platform_io.ClearPlatformHandlers() on shutdown.
// 2025-09-15: Content Scales are always reported as 1.0 on Wayland. (#8921)
// 2025-07-08: Made ImGui_ImplSDL2_GetContentScaleForWindow(), ImGui_ImplSDL2_GetContentScaleForDisplay() helpers return 1.0f on Emscripten and Android platforms, matching macOS logic. (#8742, #8733)
// 2025-06-11: Added ImGui_ImplSDL2_GetContentScaleForWindow(SDL_Window* window) and ImGui_ImplSDL2_GetContentScaleForDisplay(int display_index) helper to facilitate making DPI-aware apps.
