| 26 * The coordinate space for rectangles and points is considered | |
| 27 * to have increasing values downward and to the right from its | |
| 28 * origin making this the normal, computer graphics oriented notion | |
| 29 * of (x, y) coordinates rather than the strict mathematical one. | |

| 35 * object has been inserted. | |
