ConnectorSkeleton

```
public interface ConnectorSkeleton
```
Class used by DefaultCamera, implementation in gs-ui-... Skeleton for edges. Data stored on the edge to retrieve the edge basic geometry and various shared data between parts of the renderer. XXX TODO This part needs much work. The skeleton geometry of an edge can be various things: - An automatically computed shape (for multi-graphs and loop edges). - An user specified shape: - A polyline (points are in absolute coordinates). - A polycurve (in absolute coordinates). - A vector representation (points are relative to an origin and the whole may be rotated).
