// dear imgui, v1.86
// (demo code)
// Help:
// - Read FAQ at http:https://dearimgui.org/faq
// - Newcomers, read 'Programmer guide' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
// - Call and read ImGui::ShowDemoWindow() in imgui_demo.cpp. All applications in examples/ are doing that.
// Read imgui.cpp for more details, documentation and comments.
// Get the latest version at https://github.com/ocornut/imgui
// Message to the person tempted to delete this file when integrating Dear ImGui into their codebase:
// Do NOT remove this file from your project! Think again! It is the most useful reference code that you and other
// coders will want to refer to and call. Have the ImGui::ShowDemoWindow() function wired in an always-available
// debug menu of your game/app! 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.
// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().
// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be
// linked, you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty.
// In another situation, whenever you have Dear ImGui available you probably want this to be available for reference.
// Thank you,
// -Your beloved friend, imgui_demo.cpp (which you won't delete)
// Message to beginner C/C++ programmers about the meaning of the 'static' keyword:
// In this demo code, we frequently use 'static' variables inside functions. A static variable persists 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, to make the demo source code faster to read, faster to write, and smaller
// in size. 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 multiple threads. This might be a pattern you will want to use in your code,
// but most of the real data you would be editing is likely going to be stored outside your functions.
// The Demo code in this file is designed to be easy to copy-and-paste into your application!
// Because of this:
// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace.
// - We try to declare static variables in the local scope, as close as possible to the code using them.
// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API.
// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided
// by imgui_internal.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional
// and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h.
// Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp.
// Navigating this file:
// - In Visual Studio IDE: CTRL+comma ("Edit.NavigateTo") can follow symbols in comments, whereas CTRL+F12 ("Edit.GoToImplementation") cannot.
// - With Visual Assist installed: ALT+G ("VAssistX.GoToImplementation") can also follow symbols in comments.
