+// ImGui::CreateContext() will automatically set this pointer if it is NULL. Change to a different context by calling ImGui::SetCurrentContext().
+// 1) Important: globals are not shared across DLL boundaries! If you use DLLs or any form of hot-reloading: you will need to call
+//    SetCurrentContext() (with the pointer you got from CreateContext) from each unique static/DLL boundary, and after each hot-reloading.
+//    In your debugger, add GImGui to your watch window and notice how its value changes depending on which location you are currently stepping into.
+// 2) Important: Dear ImGui functions are not thread-safe because of this pointer. 
+//    If you want thread-safety to allow N threads to access N different contexts, you can:
+//    - Change this variable to use thread local storage so each thread can refer to a different context, in imconfig.h:
+//          struct ImGuiContext;
+//          extern thread_local ImGuiContext* MyImGuiTLS;
+//          #define GImGui MyImGuiTLS
+//      And then define MyImGuiTLS in one of your cpp file. Note that thread_local is a C++11 keyword, earlier C++ uses compiler-specific keyword.
