I couldn't realy care about the precise starting point I think. It has to be somewhere on a boundary of the node. Worst case, make it the centre of the node. This might be easy to achieve (but not that beautiful) otoh, maybe you could ask the developers (via a jira issue) to also store the starting point in gpd.xml. Using SVG is imo a much nicer way to display processdefinitions and the progress because an image and an overlay is not needed.
