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) > So we can go to 64 bit integers, or should I say, "evolve through" 64 > integers as part of our migration path.

The main reason of rollback is coming release. Currently I have 'half-roll- back' in my local branch, I working on. > I hope we can find a way to do that.

Beware the overplanning. :) I think the most essential could be implemented very soon. -- --- KeyFP: DC07 D4C3 BB33 E596 CF5E CEF9 D4E3 B618 65BA 2B61 _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
