boost::polygon writers could be wise if they're doing all if fixed point.

btw, I'm currently looking toward adoption of CGAL or so, as with all pros, 
boost have seruois cons:
- It is much overloaded with temlpates so it compiles slow and hard to debug.
- It is do not support arcs (CGAL does)

We can. Possibly it could also solve problems with overflows.

The main reason of rollback is coming release. Currently I have 'half-roll-
back' in my local branch, I working on.

Beware the overplanning. :) I think the most essential could be implemented 
very soon.
