| 872 * | |
| 873 * A coord object has a geo to keep track the range that it's members will | |
| 874 * draw on. Geo of a coord should be recomputed when the coord is changed. | |
| 875 * Geo of a coord used to accelerate finding overlay shape objects of | |
| 876 * a specified geo. A coord object also must be recomputed when one of | |
| 877 * it's members is changed. | |
| 878 * | |
| 879 * New and old geo values of a coord object that is recomputed for | |
| 880 * changing of it-self must be used to find overlay shape objects. | |
| 881 * New and old geo values of a shape should also be used to find | |
| 882 * overlay shape objects, too. If a shape's coord is changed, shape's | |
| 883 * geo object is not used to find overlay shape objects any more. | |
| 884 * | |
| 885 * steps: | |
| 886 * - update chagned coord objects | |
| 14 | 887 * - recompute area for changed coord objects |
| 13 | 888 * - recompute geo for members shape objects |
| 14 | 889 * - clear dirty of geo for members to prevent from |
| 890 * recomputing for change of shape objects. | |
| 891 * - add old and new area value to list of dirty areas. | |
| 13 | 892 * - recompute geo for changed shape objects |
| 14 | 893 * - only if a shape object is dirty. |
| 894 * - put new and old value of area of geo to list of dirty areas. | |
| 895 * - Scan all shapes and redraw shapes overlaid with dirty areas. | |
