Hi, in "AG_SDL_GenericEventLoop", I find AG_WindowDraw will draw window in every loop, even the window is valid. I want to know if i can realize the widget is invalid before drawing it. because if drawing it in every time, it will waste much source. So if i know it is valid, it will not be drew. I know there is a invalid status for widget in some other GUI. And is there the same one in agar? Further how to deal with the problem for some widgets, which need not be drew again? thanks
