// 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, 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 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.
// 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 is this file is designed to be easy to copy-and-paste in into your application!
// Because of this:
// - We never omit the ImGui:: namespace when calling functions, even though most of our code is already 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 it has been exposed in the public API (imgui.h).
// - We never use maths operators on ImVec2/ImVec4. For other imgui sources files, they are provided by imgui_internal.h w/ IMGUI_DEFINE_MATH_OPERATORS,
// 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 don't want to assume anything about your support of maths operators, we don't use them in imgui_demo.cpp.
