While not trying to provide any formal answer, I'd just like to
highlight a recent, tightly related, thread in the Batik mailing list
where this particular symptom is felt and a possible workaround
(specific to Batik) is suggested.

A relevant part of the specification seems to point towards a known
limitation: "rendering should be accurate to within one px unit to the
mathematically correct result" [2], so the gaps are probably being
caused by the anti-aliasing mechanism...

Hope this helps,
