This is a preparation patch for adding support for apps which want to change the resolution when they go fullscreen because they are hardcoded to render at a specific resolution, e.g. 640x480.
Follow up patches will fake the mode-switch these apps want by using WPviewport to scale there pixmap to cover the entire output.
