(Skipping the iteration to find one that is as far as possible from
the borders)
This makes the labels look better in many cases (like France at z1)
but unfortunately ripples into changing the sequence of polygons in
many tests, so the diff is big.
* Improve precision of get_area by using long double
* Trying to get consistent polygon area results between ARM and x86
* Calculate polygon area closer to the origin for better precision
* Update changelog
* Also exercise tiny polygon dust in the ring area test
They previously behaved differently here between x86 and ARM
* On M1 Macs, long double is just double anyway, so don't use it
* Be more careful about overflow: scale the polygon ring down into range
* Fix the bug I just introduced in the scaled area calculation
* Use only the sign from the scaled-down area calculation
