Ah segmented patch coords again.

How about a real solution to the problem of routing objects in diagrams?
 In PD this could mean a few things:

1. Best patching practise!!! Often you can choose not to overlap objects
and connections just by arranging objects as the connections force you
to, which gives you the valuable side-effect of having the position of
object show the flow of the patch more clearly.

2. Empirical tests have shown that curved (spline) connections between
nodes are actually the best way to make them easier to follow, so yay
for spline/curved connections and nay for segments! (See p193, figure
6.8 in "Information Visualization: Perception for Design" by Colin Ware.)

3. I noticed the new inkscape has some very fancy graph drawing
features, one of which is the ability to tell connections to
automatically route around nodes. They are not curved, but the idea of a
 PD where connections simply avoid objects themselves has a lot of

Of course I'm not saying adding the choice is necessarily a bad thing,
but the real question is what nurtures best practise? That remains to be
seen, but I'd be very surprised if segmented connections were it.
