docs: Coach only command.
  The online coach can send teams-graphics as 256 x 64 XPM to the server.
  Each team graphic-command sends a 8x8 tile.
  X and Y are the coordinates of this tile,
  so they range from 0 to 31 and 0 to 7 respectively.
  Each XPM line is a line from the 8x8 XPM tile.
  
  @param xpm An XPMImage object.
