-// dear imgui: Platform Backend for SDL3 (*EXPERIMENTAL*)
-// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
-// (Info: SDL3 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
-// (IMPORTANT: SDL 3.0.0 is NOT YET RELEASED. IT IS POSSIBLE THAT ITS SPECS/API WILL CHANGE BEFORE RELEASE)
-
-// Implemented features:
-//  [X] Platform: Clipboard support.
-//  [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
-//  [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
-//  [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
-//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
-// Missing features:
-//  [ ] Platform: IME SUPPORT IS BROKEN IN SDL3 BECAUSE INPUTS GETS SENT TO BOTH APP AND IME + app needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.
-
-// 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.
-// Learn about Dear ImGui:
-// - FAQ                  https://dearimgui.com/faq
-// - Getting Started      https://dearimgui.com/getting-started
-// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-//  2024-04-15: Inputs: Re-enable calling SDL_StartTextInput()/SDL_StopTextInput() as SDL3 no longer enables it by default and should play nicer with IME.
-//  2024-02-13: Inputs: Fixed gamepad support. Handle gamepad disconnection. Added ImGui_ImplSDL3_SetGamepadMode().
-//  2023-11-13: Updated for recent SDL3 API changes.
-//  2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
-//  2023-05-04: Fixed build on Emscripten/iOS/Android. (#6391)
-//  2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
-//  2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
-//  2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
-//  2023-02-07: Forked "imgui_impl_sdl2" into "imgui_impl_sdl3". Removed version checks for old feature. Refer to imgui_impl_sdl2.cpp for older changelog.
