* Work in progress on inverse spatial ordering
* Fix inverse spatial feature order
* --reorder was depending on a feature index that wasn't being preserved
* Separate ordering by feature_minzoom from ordering inverse-spatially
* Add a test for the inverse spatial ordering
* Store the basezoom/droprate/multiplier decisions in tileset metadata
* Progress on adding filters to tippecanoe-overzoom
* Type promotion for comparison
* Look up the attribute value for ordering
* Add test of thinning and ordering features
* Plumb tippecanoe_decisions metadata through pmtiles
* Be careful not to put infinities in JSON
* Fix accidental dropping in what is meant to preserve sparse points
* Start distinguishing true, false, and null in expressions
* Most of the type conversions
* Add boolean conversions
* Literals and conjunctions
* Add filtering to tippecanoe-overzoom
* Add a test of filtering in overzoom
* Fix boolean conjunctions
* Handle the combination of cluster size and filtering
* Rework dot dropping to reconcile density threshold and multiplier
* Revert "Rework dot dropping to reconcile density threshold and multiplier"
This reverts commit f253a66382.
* Retain points by multiplier within each tile, not in global probability
* Test that intends to verify that the multiplier is reversible
* Get the test to detect the discrepancy
* Mark the start of multiplier clusters with a magic attribute
* Add string-contains
* Add in and ni operators
* Revert "Look up the attribute value for ordering"
This reverts commit 56bc73e49a.
* Revert "Type promotion for comparison"
This reverts commit 6f3256f5af.
* Make number formatting in tippecanoe_decisions consistent
* Revert "Add a test for the inverse spatial ordering"
This reverts commit c8047de9ab.
* Revert "Separate ordering by feature_minzoom from ordering inverse-spatially"
This reverts commit 35b19a223c.
* Revert "Fix inverse spatial feature order"
This reverts commit 5978ecdb44.
* Revert "Work in progress on inverse spatial ordering"
This reverts commit fdf230f632.
* Somehow missed the tests associated with that last revert
* Round-robin assign attributes to partials from across the multiplier
* Count the multiplier separately in each layer
* Fix distribution of accumulated attribute across multiplier features
* Update changelog, version, and docs
* Add "is null" and "isnt null" expressions
* Update interpretation of FSL expressions to pass the tests
* Test to assert that polygons are unaffected by the multiplier
* Clean up and comment
* Remove accidental unused case
* 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
