There are two issues that are handled in this fix.
  1)File created in MSO2K10 on RT gets corrupted.The root cause is found in CustomShapeProperties::pushToPropSet
  2)File created in MSO2K7 on RT gets corrupted.There is an issue in shape import <a:gd> values for any shape (ex. circular arrow, hexagon etc).LO cannot import right <a:gd> values for any shape  which is created in MSO-2007.Due to missing values of <a:gd> tag, after roundtrip the file gets corrupted.To avoid corruption a check introduced:-
    if(aAdjustments.size() == nLength)
    after http://opengrok.libreoffice.org/xref/core/oox/source/export/drawingml.cxx#1784
    that will verify the number of <a:gd> tags associated with the shape during import and the number of <a:gd> tags during export.If there is a mismatch <a:gd> willnot be written.Changes made in DrawingML::WritePresetShape.
I have written 2 test cases for the same.
