- Actually, you just need to use the rectangle area tracking events.
- Using just two rectangles, it is possible to track any number of

- It's very very easy. Just keep all the links correct. The last child's
- ob_next points to its parent. The very last object in the form has the
- LASTOBJECT bit set.
