 893    invisible before they are updated, then some rows of the

 904    calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay,
 905    which sets visible and iconified from their asynchronous
 906    counterparts.
 907
 908    Synchronous code must use the FRAME_SET_VISIBLE macro.
 909
 910    Also, if a frame used to be invisible, but has just become visible,
 911    it must be marked as garbaged, since redisplay hasn't been keeping
