Title: Issue179 debugger drawing optimization

@ Jerome: the debugger was becoming quite slow on big scenes, and I realized that the code built a lot of geometries that were not used.

e.g.
- Each node drew a 'drop shadow', which is unnecessary.
- Each port would have 2 'event catchers' attached. These are only used when interactively building graphs. (Something I used to do).
- Each connection would draw a border and an event catcher. Neither is necessary.

With these changes, the debugger is a bit simpler, and is faster to pan and zoom.
