I guess at least width and height attributes should be conserved.
However, we should work on a more general solution that allows to pass arbitrary attributes to any sink methods. Something like (taking figure as example, this should be applied to all relevant sink methods)
public void figure( SinkEventAttributes attributes );
where SinkEventAttributes is just a Map of attribute names-values which should be parsed and processed by the receiving Sink. I'm not sure about the details yet but this would solve a couple of issues apart from the current one, eg
DOXIA-38, DOXIA-63, DOXIA-78, DOXIA-163, DOXIA-164, DOXIA-204.
