Model layout is scrambled after moving to a different tab, resizing window, and moving back

[GoogleCodeExporter]

Attached is a screenshot of what the model looks like when I do the following:
1. Run the 2PC example
2. Switch to the invariants tab
3. Resize window (larger, or smaller -- it doesn't matter which)
4. Switch to the model tab

The layout in the attached model is scrambled -- edges are not longer connected 
to nodes, and nodes are missing. If I then resize the window, the layout is 
fixed (though, in this case, the animation is no longer helpful).

A fix to this issue should re-layout the model whenever a user switches to the 
model tab. However, if the window has not been resized, the layout should not 
change (or perhaps can change very little). That is, nodes should not be flying 
around into a new layout if the user merely switched to a different tab and 
then switched back.

This is a problem again, not sure why.

This is actually resolved in the Issue78 branch. It needs to be merged into 
default to propagate.
