Summary: FILESAVE ODP: Writes wrong start coordinates in svg:d
attribute of a connector shape

Comparison of curved connector with Bézier curve
The attached file has a connector between the two rectangles. This connector
was copied and converted to a Bézier curve. Connector and Bézier curve should
produce the same svg:viewBox and svg:d attributes in file markup (besides +-
rounding differences). But you get for the connector:
svg:d="M7000 7000c0-3001 8000-5501 8000 5000"
svg:viewBox="0 0 8001 7609"
and for the Bézier curve:
svg:viewBox="0 0 8000 7608"
svg:d="M0 2608c0-3001 8000-5501 8000 5000"
The coordinates (0|2608] in the M command of the Bézier curve are correct, the
coordinates (7000|7000) in the M command of the connector curve are wrong.
Currently it has no large consequences, because LibreOffice recreates the
connector curve from the connection points ins svg:x1, svg:y1, svg:x2 and
svg:y2. But it will become a problem, if we start to use the svg:d attribute to
decide whether the curve form was created to be compatible with the OOXML
definitions or follow the LO way.
