INCOMPLETE AND OUT OF DATE

The graphics API uses a file graphics.xml that is created and occasionally modified by the core client or screensaver. This file has the format: 

    <graphics_info>
        <do_graphics/>
        <xsize>500</xsize>
        <ysize>400</ysize>
        <full_screen/>
    </graphics_info>

The graphics API implementation uses a 60 Hz timer. Every 0.5 sec, it sees if graphics.xml has been modified, and if so parses it. Every 1/60 sec, it sees if it's time for a new frame, and if so calls app_render().
