* Start to distinguish fixed cluster density setting from as-needed density
* Make consistent {drop,coalesce}-densest decisions between zooms
* Actually track the previous index instead of just intending to
* Clean up collinearities in coalesced features
* To determine densest, look at actual physical distance, not just index
* Don't actually need the previous index in serial_feature now
* Center of mass of one feature to most distant point of the next
* Add apologetic comment
* Wait, how did the tests pass before?
* Revert "Wait, how did the tests pass before?"
This reverts commit f73c8ee543.
* Add --maximum-string-attribute-length option
* Update version and changelog
* A little more testing to make sure
* Prep to track conditions other than just "dropped" or "kept"
* Count up instead of down
* Drop or retain whole multiplier clusters based on their first feature
* Calculate a global feature dropping sequence
* Switch over to using the drop sequence for drop-fraction
* Remove unused arguments for the old drop-fraction implementation
* Fix copy-and-paste bugs, update tests
* Properly incorporate feature_minzoom into the drop sequence, I hope
* Rename drop_by to drop_sequence
* See if sorting within clusters fixes filter stability between zooms
* Remove very chatty debug print
* Update changelog and version
* Use named constants instead of numbers for feature dropping/keeping
* Add comment to explain purpose and method of bit reversal
* Clip away entire features by bbox. Avoid unnecessary recompression.
* Move parent tile decoding in tile-join out of overzoom proper
* An ever-growing cache of parent tiles
* Limit the size of the cache
* Remove the current reader *before* checking if we can run the queue
* Clean up
* Add missing #include
* Add comment
* When the tile-join cache fills up, evict the least recently used
* Fix microsecond math
* Factoring out tile-join's cache for testing
* Add unit tests for tile-join cache
* Update changelog and version
* Start of externalizing polygon shard detection
* Completely untested external quicksort
* Add unit test for external quicksort
* Remember to clean up temporary files
* Sort and scan the vertices
* Bring over more vertex logic
* Make nodes from vertices
* Checkpoint on switching over to global shared nodes
* Do the thing
* Revert unintended change to coalesced linestring behavior
* Take shared nodes into account in early simplification
* Let it do more sorting in memory
* Fix overnoding of collinear linestrings
* Remove duplicate nodes, since only duplicate vertices now matter
* Remember to delete temporary files
* Fix out of bounds memory access below, apparently
* Fix the actual undefined behavior
* Still running out of memory in one case. Find out where.
* Forgot the conditional
* Try again to make it not run out of memory
* Update version and changelog
