show all port names at some zoom level about the-graph

Of course, with ports also on n/s sides this is a design challenge...

Maybe this should show them all in the highlight view?

Good example from another FBP tool:

A comment on this blog on ZUIs:

... ZUI interfacing in the RTS video game Supreme Commander
Of note:

• usage of icons to represent key items (units) in zoomed out scenarios
• locations bindable to commands/keys (much like multi-desktop functionality)
• support for multiple monitors, with each having their own customizable zoom levels, so that you can be zoomed in at one location, while working in another

@forresto going further, we could use the inside space of a node to show the component source code or minimap (for subgraphs) when zoomed really much in
