* A KnuthPenalty is a feasible breaking point unless its value is infinity;
* a KnuthPenalty whose value is -infinity represents a forced break.
*
* A KnuthPenalty is suppressed, and its width is ignored, if it is not a
* chosen breaking point; for example, a KnuthPenalty representing a
* hyphenation point has a width (the "-" width), which must be ignored if
* that point is not chosen as a breaking point.
*

* attributes and the methods used to get them: the penalty value, which is
* a kind of "aesthetic cost" (the higher the value, the more unsightly the
* breaking point), and a boolean that marks KnuthPenalties which should not
* be chosen as breaking points for consecutive lines.
