Dear MetaPost list subscribers,

the reason I moved this discussion to the list is that

(i) I wanted to start a thread about these bugs here anyway, but was
(and will be again) a few days off-line, so Karl and Boguslaw were
faster starting the discussion,

(ii) I hope there are some more people here familiar with the topic of
Bezier curves, in particular envelope calculation and perhaps the
approach taken by MetaPost.

If you think you can help in any way fixing these long-standing MetaPost
bugs, please raise your voice.  All ideas for fixing the current code as
well as implementing an alternative approach are welcome.  Thank you!

Best regards,
Stephan Hennig

nothing more to add to the issue)
