- * will contain an array of strings that have been broken down to fit the
- * box. The box's coordinates and size will reflect the size of the
- * entire group of strings if it is laid out as expected. Using the
- * returned box and iterating through the array of strings from top to
- * bottom, getting new bounding boxes for each one (with upper left
- * alignment and no padding) will result in the correct string wrap.
