Offset curve regression and oriented envelop on debbie, winnie, and berries

[robe]

I'm guessing offset curve behavior changed again.

Berries and Debbie all which are testing against geos branch are showing this regression

Commit [7be99c62a1dd9ee272a87d673960e84822a72a66/git] should fix the offsetcurve test, will look at oriented envelope now (had no idea it was implemented in terms of offsetcurve)

[Sandro Santilli <strk@…>]

In 36fcdd62/git:

Show obtained output on failure, in oriented_envelope test

References #5391

[strk]

The culprit for the change in ST_RotatedEnvelope must be this: ​https://github.com/libgeos/geos/commit/2efd5ed41009149db31b896cea98aacf765b004c

I've pushed a commit to show the obtained result, for a start

[strk]

On my system the reduced precision used by the test refactoring works also with newer GEOS. I'll wait to see a green from debbie before closing this ticket

[strk]

Also let me know if it's ok to push to the stable-3.3 branch now so that I can backport the fixes

[Sandro Santilli <strk@…>]

In 33d4a9b/git:

References #5391

[Sandro Santilli <strk@…>]

In a230dbc/git:

Don't use quad_segs<8, as newest GEOS will force a min of 8 anyway

References #5391 in stable-3.3 branch (3.3.4dev)

[strk]

Got a green: ​https://debbie.postgis.net/view/PostGIS/job/PostGIS_trunk/ Closing

I think this needs to be backported to 3.2. Before i was testing winnie on 3.11.0, and flipped her to testing GEOS 3.11 branch, she is failing on offset curve
