Right now we assume that the nodes (& edges) of the graph stay constant and we turn on/off the splines in a separate step.

Really path optimization should be a layout feature which works even if the graph is changing at the same time.

In particular:

[ ] draw_spline_paths should consider a path to be "in view" if the nodes are in the current data, not the current canvas
[x] d3v4_force_layout should not crash when it's trying to apply path forces and some of the nodes have disappeared
[x] when a path is removed, the splines of the remaining paths should update to the new node positions
