* Fix tile-join crash when trying to merge empty tilesets with --overzoom
* Add an option not to reduce tiny polygons to dust at maxzoom
* Add test for prevention of tiny polygon reduction at maxzoom
* Change version number
* Dropping a 0-length feature doesn't count as dropping-as-needed
* Add an option not to reduce tiny polygons to dust at maxzoom
* Add test for prevention of tiny polygon reduction at maxzoom
* Fix accounting for tiny polygons not to include degenerate geometries
* Revert "Add test for prevention of tiny polygon reduction at maxzoom"
This reverts commit f931bbd73e.
* Revert "Add an option not to reduce tiny polygons to dust at maxzoom"
This reverts commit 03f0882bb6.
* Fix tests
* Another test that no longer has any really tiny polygons
* Oops, that broke LineString simplification
* This time for sure!
* Update changelog and version
* 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
