Struct LineExtents 

pub struct LineExtents<T> {
    pub ascender: T,
    pub descender: T,
}

The two ends of a line, in whatever unit a caller uses.

Separate from LineBox because the gap after a line is not part of where it begins and ends, and the metrics built on a line use only the two ends.

Fields

ascender: T

Height of the line above the baseline. Never negative.

descender: T

Depth of the line below the baseline, as a negative value. Never positive.
