Impulsively did some more work improving SaVi while offline, using an ad-hoc local CVS tree I set up in a hurry.
Resulting SaVi screenshots look pretty, but now I have to figure out how best to merge that local CVS tree back into the master SaVi Sourceforge tree.
Of course, my local cvs tree has overwritten all tags, so I can't simply commit. CVS convenience comes with a concomitant cost. Aiiiieeeeee!
