i guess i missed that. i'm not seeing the fundamental design differences any 
more. the only real differences i'm seeing are in how things are actually 
drawn - OO command objects (the VObject hierarchy) vs. method commands 
(lineTo, moveTo, etc.). not really so different.

yes and no. the overall design hasn't changed. our notation classes (the ones 
responsible for drawing) are still going to be derived from something in 
there - either kshape or vcomposite. the difference is almost negligable. its 
going to be a lot of work to hand code that stuff though, but there's too 
many little variations that can be made to not hand code them. alas :)

sounds neat. i'll take a look this afternoon.
