//---- Define your own ImVector<> type if you don't want to use the provided implementation defined in imgui.h
//#include <vector>
//#define ImVector std::vector
//#define ImVector MyVector
//---- Define assertion handler. Defaults to calling assert().
//#define IM_ASSERT(_EXPR) MyAssert(_EXPR)
//---- Don't implement default clipboard handlers for Windows (so as not to link with OpenClipboard() and others Win32 functions)
//#define IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS
//---- Include imgui_user.inl at the end of imgui.cpp so you can include code that extends ImGui using its private data/functions.
//#define IMGUI_INCLUDE_IMGUI_USER_INL
//---- Include imgui_user.h at the end of imgui.h
//#define IMGUI_INCLUDE_IMGUI_USER_H
//---- Define implicit cast operators to convert back<>forth from your math types and ImVec2/ImVec4.
