-	 *
-	 * OpenGLSDLGraphicsManager "implements" saveScreenshot(const Common::String &filename) (can be overridden)
-	 * by calling the saveScreenshot(const Common::String &filename) of OpenGLGraphicsManager
-	 * and saveScreenshot() by calling saveScreenshot() of SdlGraphicsManager
-	 *
-	 * SdlGraphicsManager provides an implementation of saveScreenshot() (which can be overridden)
-	 * but a dummy implementation of saveScreenshot(const Common::String &filename)
-	 *
-	 * OpenGLGraphicsManager provides the implementation of saveScreenshot(const Common::String &filename)
-	 * but needs a (dummy) implementation of saveScreenshot() since OpenGLGraphicsManager inherits from GraphicsManager
-	 * This avoids the noisy warning (when building for OpenGL backend with no SDL support):
-	 * OpenGL::OpenGLGraphicsManager::saveScreenshot
-	 * hides overloaded virtual function
-	 * GraphicsManager::saveScreenshot
