Subject: Implement “rounded corners” setting for charts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Until now this setting was not present in the generated XML. According to the ECMA spec the setting defaults to true, so charts always had rounded corners.

Now rounded corners can be disabled explicitly.
