After a bit more thought I think it's possible to make that ^^^ nice compact non-wrapping tex lookup work with wrapping after all. It's difficult but seems like it can be done so I should look at it.
The textures would need to be doubled up to 2x2 (so 128sqr in my case) which is expensive but still much better than 256sqr which I think would be too much for this project.
The (xs/du)-u and (ys/dv)-v could be used to predict when the next wrap will occur before a sub-span is drawn and the sub span draws that many pixels plus some margin (but no more than the other axis' predicted wrap point so only 1 axis needs wrapped at a time). The u or v is then reset by one texture before the next prediction and drawing resumes.
Expensive setup involved but the 1/du stuff can be approximated with a lookup. Not sure about the rest yet - signed du,dv could be tricky. If it works it could be quite good for very long spans and when du/dv has favourable range.
