ogre 抗锯齿设置

 ogre初始化root时候可以进行设置

 Ogre::NameValuePairList misc;
		misc["externalWindowHandle"] = Ogre::StringConverter::toString((int)hWnd);
		misc["left"]="0";
		misc["top"]="0";
		
		misc["VSync"]="Yes";
		misc["VSync Interval"]="2";
		misc["FSAA"]="2"; //抗锯齿
		misc["Full Screen"]="Yes";

		SCREEN_X =GetSystemMetrics(SM_CXSCREEN);
		SCREEN_Y =GetSystemMetrics(SM_CYSCREEN);
		
		//SCREEN_X =1920;
		//SCREEN_Y =1080;
		bool isFullScreen=false;
		
		mWindow = mRoot->createRenderWindow("PuncturingRender", SCREEN_X, SCREEN_Y, isFullScreen, &misc);

或者在setup函数中再设置：

Ogre::RenderSystem::setConfigOption("FSAA","4");
	mRoot->getRenderSystem()->setConfigOption("FSAA","4");

抗锯齿不能设置的过高，渲染的代价太大
