 === Change of window size ===
-If the window size changes (e.g. switching to fullscreen mode), we have to tell the openGlRenderer what's the new window size. Otherwise e.g. the Fonts aren't scaled properly. Therefore we add an SDL Event Handler for SDL_VIDEORESIZE and submit the new window size to the openGlRenderer of CEGUI.  Also, on a resize the OpenGL context is lost, meaning textures must be reloaded.  The OpenGLRenderer provides functions to do this, grabTextures and restoreTextures.
