Fixed a bug in getGraphNodeWithNeighbourhood that was occurring when the source entity matched the stop criteria. Fixed the way maxDepth is passed down.
- Rewrote the module with more robust code.
- Derivatives images generated are now optimized.
- A configuration form has been added in the admin : it is now possible to select exactly an optimizer for each supported mime type (the priority system is gone) and to edit the optimizers options.
