Enum Affinity

pub enum Affinity {
    Upstream,
    Downstream,
}

Distinguishes between two visually distinct locations with the same byte index.

Sometimes, a byte location in a document has two visual locations. For example, the end of a soft-wrapped line and the start of the subsequent line have different visual locations (and we want to be able to place an input caret in either place!) but the same byte-wise location. This also shows up in bidirectional text contexts. Affinity allows us to disambiguate between these two visual locations.
