--------------------------------------------------------------
Noel - The Display check sounds good to me, but as mentioned elsewhere I would
prefer the EDT check to be optional if it makes sense.
Is the purpose to prevent threading issues like deadlocks, or just to ensure
that updates will be visible without an explicit repaint or some kind of layout
change, or something else?

> Doing this in AWT thread, blocks what is currently displayed.
