I think that Boost.Interpolation would be too generic and misleading
because the library's interface is more about animating than general
interpolation. For example, I think that someone searching to
interpolate the colors of the pixels of a scaled image would not find
the library really useful.

Has you have noticed, "inbetweening" is the right term in animation.
In most libraries I have seen, the term "tweener" is used to name an
object that computes the intermediate values during the movement and
the verb "to tween" is used to describe the fact that an interpolation
is done. I am not sure that there is a standard for the tween/tweener
terms.
