Hi Thomas,

I have looked at Batik.  They deal with th eproblem by implementing a 
completely new general path that uses actual arcs to draw the arcs.  
(GerenalPath is frusteratingly declared final)  This is quite a bit 
different from converting arcs to splines.  From what I remember, 
ExtendedGeneralPath also has a whole lot of dependancies.  I'd prefer to 
simply come up with the arc/spline aproximation if I can.

Also, this is for my SVG Salamander viewer, which does a lot of what 
Batik does, plus animation.   Everything is in place for paths except 
for arcs.  http://svgsalamader.java.dev.net.
