[geos-devel] Backport Intersection robustness fix (GH-937)?

[Martin Davis]

https://github.com/libgeos/geos/pull/937 switches to using DoubleDouble
computation for line intersection.  This improves the accuracy of
calculating line intersection points.

This fixes some egregious bugs in spatial predicate evaluation (e.g.
https://github.com/libgeos/geos/issues/933 and
https://github.com/locationtech/jts/issues/396).

However, It does change some overlay results.  This may cause some failures
in downstream integration tests.

Is there any objection to backporting this fix to older versions (i.e. 3.12
and possibly further back?)
