    fix bogus fb/drawable information (fixes xdemos/wincopy)
    
    the framebuffer objects attached to drawables can have invalidate state
    associated with them, since for the window framebuffer this is per-context
    state and not per-fbo state. Since drivers may rely on that information
    (otherwise would need to check if currently the window-framebuffer is
    bound in a lot of places) fix it up in _mesa_make_current (ugly).
