IgnoreFilters example for C++ 4.0 and later

This example shows how to ignore filters so that they are not loaded.

    // First, make sure PreLoaded Filters does not
    // contain CMP, and that 0 filters can be cached
    m_Lead1.PreLoadFilters(3, 0, "BMP,FAX,TIF");

    // now, ignore cmp filter (never load cmp files)
    m_Lead1.IgnoreFilters("CMP");
