This issue was about something I'd call "mathematical accuracy"
rather than "quality". (Even if I called it quality last time.)
It's very different from the quality of representing/drawing the
content. The reason is that some curves are just wrong when exported.
We should be carefull to not mix these concepts ...


About the rendering quality, I'd say that an antialiased display
in the scene is not that important. (But sure is nice to have, may be
on an optional base.) Much more important is correct and flexible
export into formats that can be used for publication ready drawings.


This is just my opinion based on some real world
problems I encountered.
