 //-----------------------------------------------------------------------------
 // COMPILE-TIME OPTIONS FOR DEAR IMGUI
 // 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 files 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.
 //#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.
 // 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 )
 //#define IMGUI_API __declspec( dllimport )

 //#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_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_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_SSE                                 // Disable use of SSE intrinsics even if available

 //---- Include imgui_user.h at the end of imgui.h as a convenience

 //---- Pack colors to BGRA8 instead of RGBA8 (to avoid converting from one to another)
 //#define IMGUI_USE_BGRA_PACKED_COLOR

 // Requires 'stb_sprintf.h' to be available in the include path. 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.
 // #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).
 // On Windows you may use vcpkg with 'vcpkg install freetype --triplet=x64-windows' + 'vcpkg integrate install'.
 //#define IMGUI_ENABLE_FREETYPE

 //---- 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                                                 \

        operator MyVec4() const { return MyVec4(x,y,z,w); }
 */

 //---- 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
 // (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: Have the Item Picker break in the ItemAdd() function instead of ItemHoverable(),
 // (which comes earlier in the code, will catch a few extra items, allow picking items other than Hovered one.)
 // This adds a small runtime cost which is why it is not enabled by default.
 //#define IMGUI_DEBUG_TOOL_ITEM_PICKER_EX

 //---- Debug Tools: Enable slower asserts
 //#define IMGUI_DEBUG_PARANOID

 //---- Tip: You can add extra functions within the ImGui:: namespace, here or in your own headers files.

 // dear imgui: Renderer Backend for OpenGL2 (legacy OpenGL, fixed pipeline)
 // This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)

 // Implemented features:
 //  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!

 // 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.
 // If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
 // Read online: https://github.com/ocornut/imgui/tree/master/docs

 // **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
 // **Prefer using the code in imgui_impl_opengl3.cpp**
 // This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read.
 // If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more
 // complicated, will require your code to reset every single OpenGL attributes to their initial state, and might
 // confuse your GPU driver.
 // The GL2 code is unable to reset attributes or even call e.g. "glUseProgram(0)" because they don't exist in that API.

 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
 //  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
 //  2021-05-19: OpenGL: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
 //  2021-01-03: OpenGL: Backup, setup and restore GL_SHADE_MODEL state, disable GL_STENCIL_TEST and disable GL_NORMAL_ARRAY client state to increase compatibility with legacy OpenGL applications.
 //  2020-01-23: OpenGL: Backup, setup and restore GL_TEXTURE_ENV to increase compatibility with legacy OpenGL applications.
 //  2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
 //  2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
 //  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
 //  2018-08-03: OpenGL: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications.
 //  2018-06-08: Misc: Extracted imgui_impl_opengl2.cpp/.h away from the old combined GLFW/SDL+OpenGL2 examples.
 //  2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
 //  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplOpenGL2_RenderDrawData() in the .h file so you can call it yourself.
 //  2017-09-01: OpenGL: Save and restore current polygon mode.
 //  2016-09-10: OpenGL: Uploading font texture as RGBA32 to increase compatibility with users shaders (not ideal).
 //  2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.

 // dear imgui: Renderer Backend for OpenGL2 (legacy OpenGL, fixed pipeline)
 // This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)

 // Implemented features:
 //  [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!

 // 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.
 // If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
 // Read online: https://github.com/ocornut/imgui/tree/master/docs

 // **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
 // **Prefer using the code in imgui_impl_opengl3.cpp**
 // This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read.
 // If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more
 // complicated, will require your code to reset every single OpenGL attributes to their initial state, and might
 // confuse your GPU driver.
 // The GL2 code is unable to reset attributes or even call e.g. "glUseProgram(0)" because they don't exist in that API.

 // [DEAR IMGUI]
 // This is a slightly modified version of stb_rect_pack.h 1.00.
 // Those changes would need to be pushed into nothings/stb:
 // - Added STBRP__CDECL
 // Grep for [DEAR IMGUI] to find the changes.

 // stb_rect_pack.h - v1.00 - public domain - rectangle packing
 // Sean Barrett 2014
 //
 // Useful for e.g. packing rectangular textures into an atlas.
 // Does not do rotation.
 //
 // 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.
