 * A justified line the breaker could not fill — a long link that breaks
 * only at its own joints, a list item whose last word cannot come up and
 * whose every hyphenation leaves a runt — would have its few word spaces
 * stretched to several times their width. Such lines are set ragged (like
 * a paragraph's last line): the text keeps its natural spacing and the
 * right edge gives instead. The ratio the line would have needed is kept
 * as `raggedSpaceRatio` (#732), which the layout reports as a `raggedLine`
 * content warning: a line left short in a justified paragraph is a thing
 * its author wants to know of. Lines within the threshold are left as
 * measured.
 *
 * A line set ragged also drops the justification tracking the breaker gave
 * it (`VDTLine.letterSpacing`, `bodyText.maxJustifyTracking`): its letters
 * go back to their natural widths too, rather than stay letter-spaced on a
 * ragged edge.
