that's good. anti-aliasing always looks nice. i remember looking at karbon and 
wondering if it might not work as a framework for uml stuff. i'd like to 
think that it would because it did look really good.

we don't expect it to add extensions. there probably isn't a good reason for 
it to do so. i mean, uml is boxes and lines (and occasionally elliptical 
shapes too).

i'm not sure what alot of that stuff means :) the editing capability we'd need 
is the ability to drop shapes onto a canvas and connect shapes with lines. 
there really doesn't need to be alot of resizing or manipulating or whatever. 
we would like to be able to click on a shape and pull up a dialog box too.

from that brief description, does it sound like it ksvg might be able to help?
