==========
This directory contains a copy of the Dear ImGui library
(https://github.com/ocornut/imgui) at the following commit :
commit f977871854af941289f2a9090dcc90f7aa3449a8
Author: omar <[email protected]>

ImFont: Minor adjustment to the structure.
Examples: Removed unused variable.
There is also a copy of the memory editor
(https://github.com/ocornut/imgui_club) at the following commit :
commit e680ad8d6b9278367d0f71a698beb96b70762ed4

imgui_memory_editor: Silence compiler warning. (#13)
Embedding the library into one's project is main way people seems to
work with ImGui. Since this is just for a debugging tool, we're not
exposing ourselves too much.
Apart from tweaking the GLEW include path, there is no other
modification to the files in this directory.

//-----------------------------------------------------------------------------
// DEAR IMGUI COMPILE-TIME OPTIONS
// Runtime options (clipboard callbacks, enabling various features, etc.) can generally be set via the ImGuiIO structure.
// You can use ImGui::SetAllocatorFunctions() before calling ImGui::CreateContext() to rewire memory allocation functions.
//-----------------------------------------------------------------------------
// A) You may edit imconfig.h (and not overwrite it when updating Dear ImGui, or maintain a patch/rebased branch with your modifications to it)
// B) or '#define IMGUI_USER_CONFIG "my_imgui_config.h"' in your project and then add directives in your own file without touching this template.
//-----------------------------------------------------------------------------
// You need to make sure that configuration settings are defined consistently _everywhere_ Dear ImGui is used, which include the imgui*.cpp
// files but also _any_ of your code that uses Dear ImGui. This is because some compile-time options have an affect on data structures.
// Defining those options in imconfig.h will ensure every compilation unit gets to see the same data structure layouts.
// Call IMGUI_CHECKVERSION() from your .cpp file to verify that the data structures your files are using are matching the ones imgui.cpp is using.
//-----------------------------------------------------------------------------
#pragma once
//---- Define assertion handler. Defaults to calling assert().
// - If your macro uses multiple statements, make sure is enclosed in a 'do { .. } while (0)' block so it can be used as a single statement.
// - Compiling with NDEBUG will usually strip out assert() to nothing, which is NOT recommended because we use asserts to notify of programmer mistakes.
//#define IM_ASSERT(_EXPR) MyAssert(_EXPR)
//#define IM_ASSERT(_EXPR) ((void)(_EXPR)) // Disable asserts
//---- Define attributes of all API symbols declarations, e.g. for DLL under Windows
// Using Dear ImGui via a shared library is not recommended, because of function call overhead and because we don't guarantee backward nor forward ABI compatibility.
// - Windows DLL users: heaps and globals are not shared across DLL boundaries! You will need to call SetCurrentContext() + SetAllocatorFunctions()
// for each static/DLL boundary you are calling from. Read "Context and Memory Allocators" section of imgui.cpp for more details.
//#define IMGUI_API __declspec(dllexport) // MSVC Windows: DLL export
//#define IMGUI_API __declspec(dllimport) // MSVC Windows: DLL import
//#define IMGUI_API __attribute__((visibility("default"))) // GCC/Clang: override visibility when set is hidden
//---- Don't define obsolete functions/enums/behaviors. Consider enabling from time to time after updating to clean your code of obsolete function/names.
//#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS
//---- Disable all of Dear ImGui or don't implement standard windows/tools.
// It is very strongly recommended to NOT disable the demo windows and debug tool during development. They are extremely useful in day to day work. Please read comments in imgui_demo.cpp.
//#define IMGUI_DISABLE // Disable everything: all headers and source files will be empty.
//#define IMGUI_DISABLE_DEMO_WINDOWS // Disable demo windows: ShowDemoWindow()/ShowStyleEditor() will be empty.
//#define IMGUI_DISABLE_DEBUG_TOOLS // Disable metrics/debugger and other debug tools: ShowMetricsWindow(), ShowDebugLogWindow() and ShowIDStackToolWindow() will be empty.
//---- Don't implement some functions to reduce linkage requirements.
//#define IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS // [Win32] Don't implement default clipboard handler. Won't use and link with OpenClipboard/GetClipboardData/CloseClipboard etc. (user32.lib/.a, kernel32.lib/.a)
//#define IMGUI_ENABLE_WIN32_DEFAULT_IME_FUNCTIONS // [Win32] [Default with Visual Studio] Implement default IME handler (require imm32.lib/.a, auto-link for Visual Studio, -limm32 on command-line for MinGW)
//#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS // [Win32] [Default with non-Visual Studio compilers] Don't implement default IME handler (won't require imm32.lib/.a)
//#define IMGUI_DISABLE_WIN32_FUNCTIONS // [Win32] Won't use and link with any Win32 function (clipboard, IME).
//#define IMGUI_ENABLE_OSX_DEFAULT_CLIPBOARD_FUNCTIONS // [OSX] Implement default OSX clipboard handler (need to link with '-framework ApplicationServices', this is why this is not the default).
//#define IMGUI_DISABLE_DEFAULT_SHELL_FUNCTIONS // Don't implement default platform_io.Platform_OpenInShellFn() handler (Win32: ShellExecute(), require shell32.lib/.a, Mac/Linux: use system("")).
//#define IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS // Don't implement ImFormatString/ImFormatStringV so you can implement them yourself (e.g. if you don't want to link with vsnprintf)
//#define IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS // Don't implement ImFabs/ImSqrt/ImPow/ImFmod/ImCos/ImSin/ImAcos/ImAtan2 so you can implement them yourself.
//#define IMGUI_DISABLE_FILE_FUNCTIONS // Don't implement ImFileOpen/ImFileClose/ImFileRead/ImFileWrite and ImFileHandle at all (replace them with dummies)
//#define IMGUI_DISABLE_DEFAULT_FILE_FUNCTIONS // Don't implement ImFileOpen/ImFileClose/ImFileRead/ImFileWrite and ImFileHandle so you can implement them yourself if you don't want to link with fopen/fclose/fread/fwrite. This will also disable the LogToTTY() function.
//#define IMGUI_DISABLE_DEFAULT_ALLOCATORS // Don't implement default allocators calling malloc()/free() to avoid linking with them. You will need to call ImGui::SetAllocatorFunctions().
//#define IMGUI_DISABLE_DEFAULT_FONT // Disable default embedded fonts (ProggyClean/ProggyForever), remove ~9 KB + ~14 KB from output binary. AddFontDefaultXXX() functions will assert.
//#define IMGUI_DISABLE_SSE // Disable use of SSE intrinsics even if available
//---- Enable Test Engine / Automation features.
//#define IMGUI_ENABLE_TEST_ENGINE // Enable imgui_test_engine hooks. Generally set automatically by include "imgui_te_config.h", see Test Engine for details.
//---- Include imgui_user.h at the end of imgui.h as a convenience
// May be convenient for some users to only explicitly include vanilla imgui.h and have extra stuff included.
//#define IMGUI_INCLUDE_IMGUI_USER_H
//#define IMGUI_USER_H_FILENAME "my_folder/my_imgui_user.h"
//---- Pack vertex colors as BGRA8 instead of RGBA8 (to avoid converting from one to another). Need dedicated backend support.
//#define IMGUI_USE_BGRA_PACKED_COLOR
//---- Use legacy CRC32-adler tables (used before 1.91.6), in order to preserve old .ini data that you cannot afford to invalidate.
//#define IMGUI_USE_LEGACY_CRC32_ADLER
//---- Use 32-bit for ImWchar (default is 16-bit) to support Unicode planes 1-16. (e.g. point beyond 0xFFFF like emoticons, dingbats, symbols, shapes, ancient languages, etc...)
//#define IMGUI_USE_WCHAR32
//---- Avoid multiple STB libraries implementations, or redefine path/filenames to prioritize another version
// By default the embedded implementations are declared static and not available outside of Dear ImGui sources files.

//#define IMGUI_STB_RECT_PACK_FILENAME "my_folder/stb_rect_pack.h"

//#define IMGUI_DISABLE_STB_RECT_PACK_IMPLEMENTATION
//#define IMGUI_DISABLE_STB_SPRINTF_IMPLEMENTATION // only disabled if IMGUI_USE_STB_SPRINTF is defined.
//---- Use stb_sprintf.h for a faster implementation of vsnprintf instead of the one from libc (unless IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS is defined)
// Compatibility checks of arguments and formats done by clang and GCC will be disabled in order to support the extra formats provided by stb_sprintf.h.
//#define IMGUI_USE_STB_SPRINTF
//---- Use FreeType to build and rasterize the font atlas (instead of stb_truetype which is embedded by default in Dear ImGui)
// Requires FreeType headers to be available in the include path. Requires program to be compiled with 'misc/freetype/imgui_freetype.cpp' (in this repository) + the FreeType library (not provided).
// Note that imgui_freetype.cpp may be used _without_ this define, if you manually call ImFontAtlas::SetFontLoader(). The define is simply a convenience.
// On Windows you may use vcpkg with 'vcpkg install freetype --triplet=x64-windows' + 'vcpkg integrate install'.
//#define IMGUI_ENABLE_FREETYPE
//---- Use FreeType + plutosvg or lunasvg to render OpenType SVG fonts (SVGinOT)
// Only works in combination with IMGUI_ENABLE_FREETYPE.
// - plutosvg is currently easier to install, as e.g. it is part of vcpkg. It will support more fonts and may load them faster. See misc/freetype/README for instructions.
// - Both require headers to be available in the include path + program to be linked with the library code (not provided).
// - (note: lunasvg implementation is based on Freetype's rsvg-port.c which is licensed under CeCILL-C Free Software License Agreement)
//#define IMGUI_ENABLE_FREETYPE_PLUTOSVG
//#define IMGUI_ENABLE_FREETYPE_LUNASVG
//---- Use stb_truetype to build and rasterize the font atlas (default)
// The only purpose of this define is if you want force compilation of the stb_truetype backend ALONG with the FreeType backend.
//#define IMGUI_ENABLE_STB_TRUETYPE
//---- Define constructor and implicit cast operators to convert back<>forth between your math types and ImVec2/ImVec4.
// This will be inlined as part of ImVec2 and ImVec4 class declarations.
/*
#define IM_VEC2_CLASS_EXTRA \
constexpr ImVec2(const MyVec2& f) : x(f.x), y(f.y) {} \
operator MyVec2() const { return MyVec2(x,y); }
#define IM_VEC4_CLASS_EXTRA \
constexpr ImVec4(const MyVec4& f) : x(f.x), y(f.y), z(f.z), w(f.w) {} \
operator MyVec4() const { return MyVec4(x,y,z,w); }
*/
//---- ...Or use Dear ImGui's own very basic math operators.
//#define IMGUI_DEFINE_MATH_OPERATORS
//---- Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.
// Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).
// Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
// Read about ImGuiBackendFlags_RendererHasVtxOffset for details.
//#define ImDrawIdx unsigned int
//---- Override ImDrawCallback signature (will need to modify renderer backends accordingly)
//struct ImDrawList;
//struct ImDrawCmd;
//typedef void (*MyImDrawCallback)(const ImDrawList* draw_list, const ImDrawCmd* cmd, void* my_renderer_user_data);
//#define ImDrawCallback MyImDrawCallback
//---- Debug Tools: Macro to break in Debugger (we provide a default implementation of this in the codebase)
// (use 'Metrics->Tools->Item Picker' to pick widgets with the mouse and break into them for easy debugging.)
//#define IM_DEBUG_BREAK IM_ASSERT(0)
//#define IM_DEBUG_BREAK __debugbreak()
//---- Debug Tools: Enable highlight ID conflicts _before_ hovering items. When io.ConfigDebugHighlightIdConflicts is set.
// (THIS WILL SLOW DOWN DEAR IMGUI. Only use occasionally and disable after use)
//#define IMGUI_DEBUG_HIGHLIGHT_ALL_ID_CONFLICTS
//---- Debug Tools: Enable slower asserts
//#define IMGUI_DEBUG_PARANOID
//---- Tip: You can add extra functions within the ImGui:: namespace from anywhere (e.g. your own sources/header files)

// Mini memory editor for Dear ImGui (to embed in your game/tools)
// Get latest version at http://www.github.com/ocornut/imgui_club
// Licensed under The MIT License (MIT)
// Right-click anywhere to access the Options menu!
// You can adjust the keyboard repeat delay/rate in ImGuiIO.
// The code assume a mono-space font for simplicity!
// If you don't use the default font, use ImGui::PushFont()/PopFont() to switch to a mono-space font before calling this.
//
// Usage:
// // Create a window and draw memory editor inside it:
// static MemoryEditor mem_edit_1;
// static char data[0x10000];
// size_t data_size = 0x10000;
// mem_edit_1.DrawWindow("Memory Editor", data, data_size);
//
// Usage:
// // If you already have a window, use DrawContents() instead:
// static MemoryEditor mem_edit_2;
// ImGui::Begin("MyWindow")
// mem_edit_2.DrawContents(this, sizeof(*this), (size_t)this);
// ImGui::End();
//

// - v0.58 (2025/03/31): fixed extraneous footer spacing (added in 0.51) breaking vertical auto-resize. (#53)
// - v0.59 (2025/04/08): fixed GotoAddrAndHighlight() not working if OptShowOptions is disabled.
//
// TODO:
// - This is generally old/crappy code, it should work but isn't very good.. to be rewritten some day.
// - PageUp/PageDown are not supported because we use _NoNav. This is a good test scenario for working out idioms of how to mix natural nav and our own...
// - Arrows are being sent to the InputText() about to disappear which for LeftArrow makes the text cursor appear at position 1 for one frame.
// - Using InputText() is awkward and maybe overkill here, consider implementing something custom.

// [DEAR IMGUI]
// This is a slightly modified version of stb_rect_pack.h 1.01.
// Grep for [DEAR IMGUI] to find the changes.
//
// stb_rect_pack.h - v1.01 - public domain - rectangle packing
// Sean Barrett 2014
//
// Useful for e.g. packing rectangular textures into an atlas.
// Does not do rotation.
//
// Before #including,
//
// #define STB_RECT_PACK_IMPLEMENTATION
//
// in the file that you want to have the implementation.
//
// Not necessarily the awesomest packing method, but better than
// the totally naive one in stb_truetype (which is primarily what
// this is meant to replace).
//
// Has only had a few tests run, may have issues.
//
// More docs to come.
//
// No memory allocations; uses qsort() and assert() from stdlib.
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
//
// This library currently uses the Skyline Bottom-Left algorithm.
//
// Please note: better rectangle packers are welcome! Please
// implement them to the same API, but with a different init
// function.
//
// Credits
