| 641 * | |
| 642 * A coord object has a geo to keep track the range that it's members will | |
| 643 * draw on. Geo of a coord should be recomputed when the coord is changed. | |
| 644 * Geo of a coord used to accelerate finding overlay shape objects of | |
| 645 * a specified geo. A coord object also must be recomputed when one of | |
| 646 * it's members is changed. | |
| 647 * | |
| 648 * New and old geo values of a coord object that is recomputed for | |
| 649 * changing of it-self must be used to find overlay shape objects. | |
| 650 * New and old geo values of a shape should also be used to find | |
| 651 * overlay shape objects, too. If a shape's coord is changed, shape's | |
| 652 * geo object is not used to find overlay shape objects any more. | |
| 653 * | |
| 654 * steps: | |
| 655 * - update chagned coord objects | |
| 14 | 656 * - recompute area for changed coord objects |
| 13 | 657 * - recompute geo for members shape objects |
| 14 | 658 * - clear dirty of geo for members to prevent from |
| 659 * recomputing for change of shape objects. | |
| 660 * - add old and new area value to list of dirty areas. | |
| 13 | 661 * - recompute geo for changed shape objects |
| 14 | 662 * - only if a shape object is dirty. |
| 663 * - put new and old value of area of geo to list of dirty areas. | |
| 664 * - Scan all shapes and redraw shapes overlaid with dirty areas. | |
| 13 | 665 * |
| 14 | 666 * dirty flag of coord objects is cleared after update. |
