The paths generated for curved connectors are basically incompatible
between LibreOffice and OOXML. Thus it was not possible to render curved
connectors the same way as MS Office. The patch adds an OOXML compatible
method for calculating the path. The new method results in a different
svg:d attribute when saved in ODF, but needs no change to ODF.
The patch introduces the boolean connector property 'EdgeOOXMLCurve' to
switch between the two methods. The property value is determined from
the svg:d attribute in case of import from ODF. In case of missing
svg:d attribute the property value is set to 'true', because Word
currently does not write a svg:d attribute when it exports to ODF.
The property value is set to 'true' for import of connectors on a
drawing canvas in docx. Default value for new connectors is 'false'.
The new property has no UI, but can be used via macro.
Currently the new method is used for import of curved connectors on
drawing canvas in docx documents.
