A graphics screen can update its internal state in this method.

This method is called automatically by the GraphicsManager once per frame before the screen needs to be rendered. The screens are updated in front-to-back order as they are registered in the GraphicsManager. Only visible screens are updated. That means, if a screen is hidden by another screen in front of it, it is not updated. The GraphicsManager checks the Coverage property of the foreground screens to determine whether a screen in the background is visible.
