oox smartart, accent process: adjust size of connector from constraints

The constraints explicitly said that the width should be larger than the
height, but it was the opposite as constraints were not parsed.

Unfortunately it would be too brave for globally start handling all
constraints which lack a forName, so add a switch to opt in for this,
and use that with the conn algorithm. All clients should migrate to
bRequireForName=true at some stage, though.
