* Add an option to retain N times as many points as usual at each zoom * Tests for point multipler with specified and guessed maxzooms * 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 commitf253a66382. * 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 commit56bc73e49a. * Revert "Type promotion for comparison" This reverts commit6f3256f5af. * Make number formatting in tippecanoe_decisions consistent * Revert "Add a test for the inverse spatial ordering" This reverts commitc8047de9ab. * Revert "Separate ordering by feature_minzoom from ordering inverse-spatially" This reverts commit35b19a223c. * Revert "Fix inverse spatial feature order" This reverts commit5978ecdb44. * Revert "Work in progress on inverse spatial ordering" This reverts commitfdf230f632. * 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
