That is not my point. If the SVG describes jagged outlines, then be it.

The issue is the inconsistent rendering across viewers.

Perhaps the spec needs to be more clear about such things. As soon as I 
have consistent rendering, I have the power to change the curves to be 
jagged or smooth, and I then get the same result in all viewers.

Then ASV and CSV need to change, I don't care who changes his rendering. 
I, and I would suspect all other SVG developers, want&need consistent 
rendering across all implementations, specified by the spec.

If Batik is behaving correct in your view, then I could file reports to 
Adobe and Corel, but I would need clear paragraphs in the spec to show them.

I think the issue is the spec; not Batik or the SVG.

Such "real work" comments are IMHO not helpful. A graphic designer does 
"real work", with "real tools", and needs to get really predictable and 
consistent results. Difference in rendering is not useful when doing 
"real work". *Especially* when doing professional graphic work.
