// dear imgui, v1.66 WIP
// (demo code)
// Message to the person tempted to delete this file when integrating ImGui into their code base:
// Don't do it! Do NOT remove this file from your project! It is useful reference code that you and other users will want to refer to.
// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().
// During development, you can call ImGui::ShowDemoWindow() in your code to learn about various features of ImGui. Have it wired in a debug menu!
// Removing this file from your project is hindering access to documentation for everyone in your team, likely leading you to poorer usage of the library.
// Note that you can #define IMGUI_DISABLE_DEMO_WINDOWS in imconfig.h for the same effect.
// If you want to link core ImGui in your final builds but not those demo windows, #define IMGUI_DISABLE_DEMO_WINDOWS in imconfig.h and those functions will be empty.
// In other situation, when you have ImGui available you probably want this to be available for reference and execution.
// Thank you,
// -Your beloved friend, imgui_demo.cpp (that you won't delete)
// Message to beginner C/C++ programmers about the meaning of the 'static' keyword: in this demo code, we frequently we use 'static' variables inside functions.
// A static variable persist across calls, so it is essentially like a global variable but declared inside the scope of the function.
// We do this as a way to gather code and data in the same place, just to make the demo code faster to read, faster to write, and use less code.
// It also happens to be a convenient way of storing simple UI related information as long as your function doesn't need to be reentrant or used in threads.
// This might be a pattern you occasionally want to use in your code, but most of the real data you would be editing is likely to be stored outside your functions.
