I think that this distinction is nonsense, a vector map has a certain
resolution just like a georeferenced bitmap has. Is it possible to
trace a bitmap map (therefore recreating vectors)? Definitely yes,
even if this might no easily or at all be possible in automated manner
(maybe if you have an "intelligent" program you might be able to do it
automatically, but I don't know any proof for this).
