For those of you who haven't had the pleasure of seeing Michael's spline paths in action, I added a new interactive demo on the trunk: examples/event_handling/path_editor.py Click and drag the vertices to edit the spline path. It needs some more work - eg I want to be able to add and delete vertices, which means tracking groups (all related CURVE4 vertices for example) and the ability to add a curve4, lineto, eg... But with a little work we'll have inkscape-lite. Just need to add some load/save features... JDH
