Yes, this is what I was about to reply. There is a bit of a fudge factor
I allowed myself in the cairo implementation, where it would actually
invalidate 1px wider than you passed due to anti-aliasing, but I don't
think this should be expanded in the general case.

Was this a bug without the magnetic net mode? If so, I'll try to
remember it needs backporting for a 1.4.1 release.

We should probably do 1.4.1 soon actually. I hope to get the gnetlist
test suite in before then, and Ales wanted intltool disabling - which I
agree is probably a good idea.

Best wishes,
