/**
 * This class holds a width and height value pair. This is used in plenty
 * of windowing classes, but also has geometric meaning.
 *
 * <p>It is valid for a dimension to have negative width or height; but it
 * is considered to have no area. Therefore, the behavior in various methods
 * is undefined in such a case.
 *
 * <p>There are some public fields; if you mess with them in an inconsistent
 * manner, it is your own fault when you get invalid results. Also, this
 * class is not threadsafe.
