Smooth panning, zooming

[w-jablonski]

Hi and thanks for this great app, very smart indeed, although I hope you intend to keep working on it and make it brilliant. Could you implement sth like smooth panning, so that upon releasing the mouse the motion gently slows down rather than stopping immediately. Also smoother zooming too. These two struck me most on first use.

Also, do you know of any rust bindings for the EFL in the making?

Thanks!
