E.g. gimp can do it.

We have all the code for screenshooting, but no binding. See
e.g. fillets -demo's "0" -key.

They are on a circle.

I've heard this from others, too. But I'm still very much convinced that
it's more important to retain

        "If I go right, I go back by going left"

than

        "Buoys should be really close to their anchors".

The problem is that with free placement, the buoys will easily go around,
resulting in a much harder-to-understand motion between nodes.

I'm thinking of a gamma correction screen at startup, or something.

Not sure yet.
