Add an option to include scaled image of earth during screenshot/movie creation

[Keith Hughitt]

In order to help people to understand the scale of events they see they images and movies, it would be helpful to provide an option during screenshot and movie creation to include a scaled image of the earth, e.g. in the bottom-right of the image/movie.

This could also potentially be done using Canvas so that the original video does not need to be modified.

Other ideas: Allow user to choose one of several reference points (e.g. Mars, Jupiter, etc)

Might also be useful to have a floating, choosable size scale in the
bottom left hand of the viewer window, or at the top left hand of the
viewer window associated with the zoom tool.

What happens when the Earth is too small to be a sensible size, i.e., a few pixels to less than one pixel? We could replace the Earth/blue dot with a simple bar that represents a number of Earths, with the number of earths indicates. A mouse hover would give slightly more explicit information.
