Chaos Yu

If you need this kind of features, personally i prefer [imgui](https://github.com/ocornut/imgui), it is useful for editors and build-in debug, it also has a lua binding [here](https://github.com/patrickriordan/imgui_lua_bindings).

Of curse, I can try to implement the Windows version, though I am not familiar with win32. :)

added the defos.toggle_maximize and defos.is_maximize for Windows, but i have to restore the fullscreen state first

Later I will have a try too, though i am not familiar with c/c++. :)
