* Put all of this back in geometry.cpp for conflict resolution
* Stabilize line simplification to behave the same regardless of winding
* Round instead of truncating when clipping lines
* Restore non-Wagyu polygon clipping from prior to 2fdec7d2
* Make it round, not truncate, which reverts the last commit's test diffs
* Clip in floating point, not integers, which makes no difference
* Track nodes added at tile edges during clipping
* Scale geometry up before wagyu to prevent changes from precision loss
* Actually do the shared edge detection
* Fix cases where nodes were not being added at the tile boundary
* One more place I should have rounded
* Narrow down where the discrepancy comes in
* Revert "Narrow down where the discrepancy comes in"
This reverts commit 221c4c5fc0ac9a6567e091c6a94b3d87dc8ade83.
* Another attempt to narrow it down
* The discrepancy seems to be introduced in reordering. No obvious bug
* Was still truncating instead of rounding in projection
* Also makes no difference...
* Just forget that line reversal exists for a minute
* Just reversal no coalescing
* Try clipping in integers instead of floating point
* Don't simplify after coalescing if they said no simplification
* Check whether behavior is consistent with intentional simplification
* Replace more floating point with integer
* Are these three features enough to demonstrate the problem?
* Add a few more nearby borders
* All the features that touch tile 6/16/23
* Stay in integers in line simplification
* More attempts to solve failures to simplify consistently
* Fix most of the overflow errors
* Fix known cases of integer overflow
* All the tests change again
* Pull clipping and scaling code back out into clip.cpp
* Resolve the test conflicts
* Stabilize choice of which three points to keep with different windings
* Almost right, I think!
* Fix collapse of islands to shards
* Self-intersections in the same feature don't count
* Revert "Self-intersections in the same feature don't count"
This reverts commit e04b19916e.
* Don't scale down geometry if we are going to look for shared nodes
* Fix the missing multiply that was keeping simplification from happening
* Fix one more opportunity for overflow
* Somehow I deleted this test?
* Lost this test too
* Clean up debugging printfs
* Restore code sequence from main to make it reviewable
* Remove unneeded rounding
* Update documentation
* This test is no longer useful
* Back to floating point Douglas-Peucker to fix undersimplification
* Try an older ubuntu
* Revert "Try an older ubuntu"
This reverts commit 13fefacfd7.
* Log OS info
* Remove tests that are no longer needed
* Oops, did need that one after all
* Fix the arm vs x86 discrepancy?
* Try another quantization
* Cleanup from review
* Add a test for the actual purpose of this PR
* Add an option to extend zooms if still dropping, but with a limit
* At least when to overzoom, even if not actually doing it yet
* Refactor to give tile-join access to overzoom()
* Didn't work, but *might* have worked
* OK, it did something now
* Ah, there's the bug!
* Hook up pmtiles and dirtiles as overzooming sources
* Add command line option to enable or disable overzooming
* Add (currently broken) test of overzooming in tile-join
* Slightly more abstraction for the tile-join readers
* Factor out duplicated code
* Move construction into a constructor
* More changing accessors to methods
* Reduce magic
* Start tracking a list of the tiles at maxzoom
* I think it worked?
* Add missing #include
* Fix sequence of overzoomed tiles (Y sorts backwards for TMS)
* Don't spend memory on overzooming when we aren't going to use it
* Diff rather than cmp, in the hope of figuring out this broken test
* Keep full coordinate precision if we might extend zooms
* Try a slightly different byte limit
* Make drop-densest more consistent across tile boundaries
* Also affects this test
* Does it behave any differently if it can extend forever?
* I think the discrepancy is a thread-safety problem here
* Revert "Does it behave any differently if it can extend forever?"
This reverts commit 0dff0a0acc.
* Lost this change to the test
* This time for sure!
* Revert "Also affects this test"
This reverts commit cd1f7c2e78.
* Revert "Make drop-densest more consistent across tile boundaries"
This reverts commit 563f7d2bc2.
* Revert "Try a slightly different byte limit"
This reverts commit 2e271213d6.
* Add some more explanatory comments
* Amend the join-test to detect my current bug
* Allow overzooming to complete the zoom if it ever starts
* Forgot to correct the test
* Update changelog and version
* Cleanups from code review
* Remove version number from fixture to fix test
* Starting work on overzooming
* Factor clipping out of geometry.cpp to simplify linkage
* Pull out more geometry functions into now-badly-named clip.cpp
* Not surprisingly, there is a bug
* Found the bug
* Make indent
* Pass attributes through
* Make formatting more consistent
* Fix typos in comments
* Fix the typos better
* Add tippecanoe-overzoom to the install list
* Give overzoom a predictable exit status
* Forgot to translate to and from polygon ring closepaths
* Fix geometry collapse at z21
* Add attribute stripping; don't generate layers if they have no features
* Add docs for tippecanoe-overzoom (as it will be, not as it is)
* Change overzoom to accept input and output files as arguments
* Working on overzooming tests
* Oops
* Hook up and test the detail and buffer options, and the empty-tile case
* Also test attribute stripping
* Fix error message
* Update changelog and version
