(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

* First attempt at porting Paul Mach's Visvalingam implementation
* Make indent
* Mostly working
* Approximate equivalence from Douglas-Peucker to Visvalingam levels
* Don't simplify away tile boundary crossing points
* Add a command-line option and test for Visvalingam simplification
* Update changelog
* Cleanup in response to review feedback
* Include <stdio.h> to fix compiler warnings
* Stop adding features to a tile if it can't possibly work
* Add --integer and --fraction options to tippecanoe-decode
* Carry the strategies field from tileset metadata through tile-join
* Update changelog
* Assign different codes to different kinds of error exits
* Reduce maxzooms being guessed a little:
* Use 1.5 standard deviations, not 2, as the minimum distinguishable
* Give overlapping polygons and linestrings more distinct indices
* Add another drop rate guessing options, from the same metrics -zg uses
* Guard against using -rp without -zg
* Add an option to retain extra coordinate precision at maxzoom
* Make sure not to shift away the extra detail from coordinates
* Add an option to convert double-precision attributes to single
* Sort attribute values in tiles to make them compress a little better
* Slightly improve polygon simplification
By choosing a point that would be retained after simplification
to be the start/end point that always gets retained
* I regret making all of these tests involve polygons
* Add an option to specify the size of tiny polygons
* Fix accidental requiring of argument for --single-precision
* Guard against duplicate points when generating "sizes" for them
* Restore the intended behavior that tiny polygons don't get simplified
* Make the extra detail settable rather than always maximizing it
* Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)"
This reverts commit fec5e8354c.
* Add an option to prevent choosing a base zoom higher than the maxzoom
* Keep the drop rate high enough when the basezoom gets constrained
* Revert "Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)""
This reverts commit db6bc27d9e.
* Add --order-by and --order-descending options
* Accept multiple --order-by and --order-descending-by sort keys
* Improve maxzoom guessing for tightly-clustered point data sources
* Go back to the old distance estimate, since it is less mysterious
* Update changelog and version
* Add --maximum-zoom-at-least to specify a minimum maxzoom to guess
* Check whether the specified minimum maxzoom is out of range
* Rename the option to --smallest-maximum-zoom-guess
* Update tests, changelog, and version
* Handle points too when dropping or coalescing the "smallest" features.
* Add statistics of tile size reduction strategies to tileset metadata
* Update changelog and version
* Update documentation
* Change JSON objects to a union type to use less memory
* Stop storing the string representation of JSON numbers
* Restore the ability to create features with large integer attributes
* Make sure large-integer feature IDs still behave as before
* Add missing #include
* Don't preallocate as much space for arrays and objects
* Treat inability to check free disk space as a warning, not an error
* Update changelog and version
