Nothing has changed in that respect except that some new functions have 
been designed and now a ProjectionBounds class exists.

It should only be clear that EastNorth ist not stored. These value are 
projection depending and are not reliable. But in all cases I found it was 
easy to fix storing of these values.

The Node class stores these values nevertheless (to reduce calculation 
efforts for display) but takes care to update when projection changed.
