         In DV 2.00:
                BYTE DS:[0] = window number
                WORD DS:[1] = segment of other data structure
                WORD DS:[3] = segment of window's object handle
Direct Screen:  0 = Program does not do direct write
                1 = Program does direct writes, so shadow buffer not usable
Note:   This function is probably meant for internal  use only,
        due to the magic value required in DX |
