Applet using Batik to allow the displaying of Workflows within the repository

"Looks like it would be easy to have an exact replication of Taverna's diagram viewer as part of the repository. The task would be to implement the viewer part as an applet (this may be trivial, I think batik is designed to be applet friendly) and then modify Taverna's diagram panel so it could call back to the server to get the appropriate SVG based on the display settings.

This would mean we could give the user the zoom and pan abilities that they'd have in the full workbench along with the various level of detail controls, I reckon this is maybe a week's work to get up and running including learning how to use the batik APIs?"
