Zoom / Pan Listener or Camera Idle Callback about react-force-graph

[vasturiano]

@GeoffGodwin yes you're right, tbControls doesn't exist in 2D. It's a different zoom/panning mechanism, based on d3-zoom.
So, there isn't currently a way to detect pan/zoom user interactions from outside the component.
I can imagine adding an event notifier (say onZoomPan()) at every interaction, if there's enough interest in the feature.
For future reference, that should be triggered here:

@GeoffGodwin how do you define camera idle? Can you detect from the trackball controls, perhaps with the end event?
If so, you can access it using the tbControls() method. Try it, it may work. :)

@vasturiano I'm actually using the 2D and I believe the tbControls() is only available in 3D unless I'm wrong?

@vasturiano onZoomPan() would be an amazing feature if it gets added, I currently have a use case of limiting the max and min zoom of the canvas, will try with the above suggestion for now.
