// dear imgui: Platform Backend for SDL3
// This needs to be used along with a Renderer (e.g. SDL_GPU, DirectX11, OpenGL3, Vulkan..)
// (Info: SDL3 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 are obsolete since 1.87 and not supported since 1.91.5]
// [X] Platform: Gamepad support.
// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// [X] Platform: IME support.
// 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)
// 2025-04-22: IME: honor ImGuiPlatformImeData->WantTextInput as an alternative way to call SDL_StartTextInput(), without IME being necessarily visible.
// 2025-04-09: Don't attempt to call SDL_CaptureMouse() on drivers where we don't call SDL_GetGlobalMouseState(). (#8561)
// 2025-03-30: Update for SDL3 api changes: Revert SDL_GetClipboardText() memory ownership change. (#8530, #7801)
// 2025-03-21: Fill gamepad inputs and set ImGuiBackendFlags_HasGamepad regardless of ImGuiConfigFlags_NavEnableGamepad being set.
// 2025-03-10: When dealing with OEM keys, use scancodes instead of translated keycodes to choose ImGuiKey values. (#7136, #7201, #7206, #7306, #7670, #7672, #8468)
// 2025-02-26: Only start SDL_CaptureMouse() when mouse is being dragged, to mitigate issues with e.g.Linux debuggers not claiming capture back. (#6410, #3650)
// 2025-02-24: Avoid calling SDL_GetGlobalMouseState() when mouse is in relative mode.
// 2025-02-18: Added ImGuiMouseCursor_Wait and ImGuiMouseCursor_Progress mouse cursor support.
// 2025-02-10: Using SDL_OpenURL() in platform_io.Platform_OpenInShellFn handler.
// 2025-01-20: Made ImGui_ImplSDL3_SetGamepadMode(ImGui_ImplSDL3_GamepadMode_Manual) accept an empty array.
// 2024-10-24: Emscripten: SDL_EVENT_MOUSE_WHEEL event doesn't require dividing by 100.0f on Emscripten.
// 2024-09-03: Update for SDL3 api changes: SDL_GetGamepads() memory ownership revert. (#7918, #7898, #7807)
// 2024-08-22: moved some OS/backend related function pointers from ImGuiIO to ImGuiPlatformIO:
// - io.GetClipboardTextFn -> platform_io.Platform_GetClipboardTextFn
// - io.SetClipboardTextFn -> platform_io.Platform_SetClipboardTextFn
// - io.PlatformSetImeDataFn -> platform_io.Platform_SetImeDataFn
// 2024-08-19: Storing SDL_WindowID inside ImGuiViewport::PlatformHandle instead of SDL_Window*.
// 2024-08-19: ImGui_ImplSDL3_ProcessEvent() now ignores events intended for other SDL windows. (#7853)
// 2024-07-22: Update for SDL3 api changes: SDL_GetGamepads() memory ownership change. (#7807)
// 2024-07-18: Update for SDL3 api changes: SDL_GetClipboardText() memory ownership change. (#7801)
// 2024-07-15: Update for SDL3 api changes: SDL_GetProperty() change to SDL_GetPointerProperty(). (#7794)
// 2024-07-02: Update for SDL3 api changes: SDLK_x renames and SDLK_KP_x removals (#7761, #7762).
// 2024-07-01: Update for SDL3 api changes: SDL_SetTextInputRect() changed to SDL_SetTextInputArea().
// 2024-06-26: Update for SDL3 api changes: SDL_StartTextInput()/SDL_StopTextInput()/SDL_SetTextInputRect() functions signatures.
// 2024-06-24: Update for SDL3 api changes: SDL_EVENT_KEY_DOWN/SDL_EVENT_KEY_UP contents.
// 2024-06-03; Update for SDL3 api changes: SDL_SYSTEM_CURSOR_ renames.
// 2024-05-15: Update for SDL3 api changes: SDLK_ renames.
// 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.

// dear imgui: Renderer Backend for SDL_Renderer for SDL3
// (Requires: SDL 3.1.8+)
// Note that SDL_Renderer is an _optional_ component of SDL3, which IMHO is now largely obsolete.
// For a multi-platform app consider using other technologies:
// - SDL3+SDL_GPU: SDL_GPU is SDL3 new graphics abstraction API.
// - SDL3+DirectX, SDL3+OpenGL, SDL3+Vulkan: combine SDL with dedicated renderers.
// If your application wants to render any non trivial amount of graphics other than UI,
// please be aware that SDL_Renderer currently offers a limited graphic API to the end-user
// and it might be difficult to step out of those boundaries.
// Implemented features:
// [X] Renderer: User texture binding. Use 'SDL_Texture*' as texture identifier. Read the FAQ about ImTextureID/ImTextureRef!
// [X] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset).
// [X] Renderer: Texture updates support for dynamic font atlas (ImGuiBackendFlags_RendererHasTextures).
// [X] Renderer: Expose selected render state for draw callbacks to use. Access in '(ImGui_ImplXXXX_RenderState*)GetPlatformIO().Renderer_RenderState'.
// You can copy and 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
// 2025-06-11: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas. Removed ImGui_ImplSDLRenderer3_CreateFontsTexture() and ImGui_ImplSDLRenderer3_DestroyFontsTexture().
// 2025-01-18: Use endian-dependent RGBA32 texture format, to match SDL_Color.
// 2024-10-09: Expose selected render state in ImGui_ImplSDLRenderer3_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
// 2024-07-01: Update for SDL3 api changes: SDL_RenderGeometryRaw() uint32 version was removed (SDL#9009).
// 2024-05-14: *BREAKING CHANGE* ImGui_ImplSDLRenderer3_RenderDrawData() requires SDL_Renderer* passed as parameter.
// 2024-02-12: Amend to query SDL_RenderViewportSet() and restore viewport accordingly.
// 2023-05-30: Initial version.

// dear imgui: Renderer Backend for SDL_Renderer for SDL3
// (Requires: SDL 3.1.8+)
// Note that SDL_Renderer is an _optional_ component of SDL3, which IMHO is now largely obsolete.
// For a multi-platform app consider using other technologies:
// - SDL3+SDL_GPU: SDL_GPU is SDL3 new graphics abstraction API.
// - SDL3+DirectX, SDL3+OpenGL, SDL3+Vulkan: combine SDL with dedicated renderers.
// If your application wants to render any non trivial amount of graphics other than UI,
// please be aware that SDL_Renderer currently offers a limited graphic API to the end-user
// and it might be difficult to step out of those boundaries.
// Implemented features:
// [X] Renderer: User texture binding. Use 'SDL_Texture*' as texture identifier. Read the FAQ about ImTextureID/ImTextureRef!
// [X] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset).
// [X] Renderer: Texture updates support for dynamic font atlas (ImGuiBackendFlags_RendererHasTextures).

// stb_rect_pack.h - v1.01 - public domain - rectangle packing

// #define STB_RECT_PACK_IMPLEMENTATION

//
// Has only had a few tests run, may have issues.

//
// No memory allocations; uses qsort() and assert() from stdlib.
// Can override those by defining STBRP_SORT and STBRP_ASSERT.

* @brief Creates a new window with specified title and dimensions
* @param title Null-terminated string containing the window title text
* @param width Window width in pixels
* @param height Window height in pixels
* @return Pointer to the newly created Window object, or nullptr on failure
*
* @pre title must not be nullptr and should contain valid display text
* @pre width and height must be positive values within system display limits
* @post A new Window object is allocated and initialized with the specified parameters
* @post The returned Window pointer is ready for use with window management functions
*
* @details This function creates a new Window instance with the specified
* title and dimensions. It handles the underlying window system
* initialization, memory allocation, and setup required to create
* a functional window object.
*
* The window creation process includes:
* - Memory allocation for the Window structure
* - Initialization of window properties (title, dimensions, state)
* - Registration with the window management system
* - Setup of default window behavior and event handling
*
* The returned window pointer can be used with other window management
* functions to display content, handle events, and manage the window
* lifecycle. The caller is responsible for properly managing the window
* lifetime and ensuring proper cleanup when the window is no longer needed.
*
* @note The returned pointer must be properly managed by the caller
* @note Window resources should be freed when no longer needed
* @note The title string is copied internally and can be safely modified
* or freed after this function returns
*
* @see Window class for window object interface and methods
*
* Example usage:
* @code
* auto* window = CreateWindow("System Control", 800, 600);
* if (window != nullptr) {
* // Use the window...
* // Clean up when done
* }
* @endcode
