Enum Baseline 

pub enum Baseline {
    Normal,
    Super,
    Sub,
}

Which line a glyph sits on relative to the text around it.

Not a Role, because a raised glyph keeps whatever it already was — the 1 of a footnote reference is still a link, an author’s ^2^ inside a heading is still heading text. And not one of Style’s bool flags, because unlike bold-and-italic these do not compose: a glyph is raised, or lowered, or neither, and two flags would let a caller ask for both.

A frontend that ignores this draws every glyph on the normal baseline, which is what every frontend did before the variant existed.

Variants

Normal

The ordinary text baseline.

Super

Raised and typically drawn smaller — an author’s ^x^, and the label of a footnote reference.

Sub

Lowered and typically drawn smaller — an author’s ~x~.
