	  ( | ); | 
      Get drawing mode.  Note only one device driver (cairo) currently
      supports this at the moment, and for that case the PLINT value
      returned by this function is one of
      PL_DRAWMODE_DEFAULT,
      PL_DRAWMODE_REPLACE,
      PL_DRAWMODE_XOR, or
      PL_DRAWMODE_UNKNOWN. This function returns
      PL_DRAWMODE_UNKNOWN for the rest of the
      device drivers.  See also plsdrawmode.
    
      Redacted form: plgdrawmode()
    
This function is used in example 34.
