Subject: [PATCH] Fix Bugs about Renderer We have met a runtime error with
 SDL_IsClipEnabled. There is not solution to it yet, so we just disable it.
 Fix Bug in Window::_setRenderer_Real. smart pointer rnd is now reset first.
 (We have known that smart pointers will only change its value when it has the
 exact new value.)
