no way to easily tell whether a node has a loop edge

[nsajko]

After giving Graphia a GML file which includes edges that are loops, the graph seems displayed very nicely, but the problem is that there's no way to tell at a glance whether a node has a self edge.

The only indication seems to be the in-degree and out-degree, which are both one greater than the number of displayed edges.

This is an example of a line in the GML file defining the loop:

edge [ source 00042 target 00042 ]

I think there are two ways to solve this, and any of the two would be alright, and both even better:

1. Add loops to the 3D display, where the other edges already are displayed.
2. Enable making Visualizations which would highlight nodes with loops on them.

I hope I haven't missed anything.
