示例1: collectHorizontalBoxCoordinates
/**
* Traverses the horizontal inline boxes and appends the point coordinates to
* the given array.
* @param box inline box
* @param pointArray array collecting coordinates
* @param bottom \c true, collect bottom coordinates, \c false, collect top
* coordinates.
* @param limit lower limit that an y-coordinate must at least reach. Note
* that limit designates the highest y-coordinate for \c bottom, and
* the lowest for !\c bottom.
