    WIP ODF import and export for MCGR
    
    Current state uses:
    Element loext:gradient-stop with the attributes svg:offset,
    loext:color-type with value 'rgb', and loext:color-value with
    values of kind #rrggbb.
    Element loext:opacity-stop with the attributes svg:offset and
    svg:stop-opacity, both with datatype double.
    
    With MCGR enabled testColorGradientWithTransparencyDOCX in
    CppunitTest_chart_export3 has the value 90000 instead of
    90196. That is same value as in original file. Thus I have
    adapted the test.
