// dear imgui: single-file wrapper include
// We use this to validate compiling all *.cpp files in a same compilation unit.
// Users of that technique (also called "Unity builds") can generally provide this themselves,
// so we don't really recommend you use this in your projects.
// Users of that technique (also called "Unity builds") can generally provide this themselves easily.
// Do this:
// #define IMGUI_IMPLEMENTATION
// Before you include this file in *one* C++ file to create the implementation.
// #include "imgui_single_file.h"
// In *one* C++ file to create the implementation.
// Using this in your project will leak the contents of imgui_internal.h and ImVec2 operators in this compilation unit.

#if defined(IMGUI_IMPLEMENTATION) && !defined(IMGUI_DEFINE_MATH_OPERATORS)
