LevelLowBit example for C++ 4.0 and later

This is also the example for LevelHighBit.

This example sets LevelLowBit and LevelHighBit to display the image using only the eight least significant bits.

    m_Lead1.SetAutoRepaint(FALSE);
    //use least significant 8 bits
    m_Lead1.SetLevelLowBit(0);
    m_Lead1.SetLevelHighBit(7);

    m_Lead1.SetAutoRepaint(TRUE);
