// dear imgui: Platform Backend for SDL2
// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3,
// Vulkan..) (Info: SDL2 is a cross-platform general purpose library for
// handling windows, inputs, graphics context creation, etc.)

// 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'. [X] Platform: Multi-viewport support
//  (multiple windows). Enable with 'io.ConfigFlags |=
//  ImGuiConfigFlags_ViewportsEnable'.
// 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). [x] Platform: Basic IME support. 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).
