Hmm, ok. I hoped the problem would be not that severe because the
cubics are drawn correctly on screen.

Ok, thanks. Let's see what we can do about this issue.

Thanks for commiting. The only problem I found is related to
my own coding faults when dealing with default linewidts.
The current version gives to thick lines by default.

So I attach you a new small patch with more correct defaults.

Do you think we nee more tunig of the linewidth parameters?
The values seem to be reasonable except maybe the thickest ones.

Btw: we do not have different styles for dots. Should we support
that or just stick to the round dots?

Ah, these were some small corrections done when I came along the
code anyway. I hope this does not introduce major problems.
