I think the regressions we were having have been largely resolved.
The main regression was for our proj cache overflow tests, which doesn't
even care about the answers
but more that the timing isn't horrible.

But I think for that we have now settled on 100 someodd srids that don't
break on proj 4.9 - 9.2
regardless what the proj settings are.

Most of the ones where we check answers I think are working fine cause they
never relied on grid shifts.
