* Track output position at the file level instead of within each tile * Track file position where the child tile data begins * Add option and document its intended behavior * Changing the detail loop to account for stopping early * I forgot I already added an option for this * Stop early if we can make a complete tile * Add a test of zoom truncation with limited feature count * Forgot to commit the actual code change * Make room for a vertex count in the header of each serialized tile * Estimate tile complexity; don't try truncating when unlikely to work * Be more conservative, because ever retrying a tile is a big speed hit * If stopping early, don't simplify or clean; leave that to overzoom * Add tiny polygon reduction / dust to overzoom * Don't try to stop early in the children if we dropped anything by rate * Fflush here too before pwriting * Don't stop early if we ended up dropping any features. Rework the can-the-next-zoom-stop-early logic to avoid going one zoom further than needed. * Fix warning * Fix warnings * Oops, checking for the wrong expected return value * Cleanup from adding line simplification in overzoom * Current (wrong) behavior when combining coalescing and truncating * Keep a list of parent tiles to skip rather than truncating * Now the coalesced tiles in z12 get children in z13 * Don't double-count feature dropping when the zoom level is retried * Correct README description * Remove todo about special case below basezoom, which is accounted for * Be a little more aggressive in drop-densest determination * Scale tile feature limit for megatiles in the same way as byte limit * Fully deprecate -detect-shared-borders into an alias * Track the distances found in the douglas-peucker recursion * Serialize and deserialize the distance with the vertices * Revert "Serialize and deserialize the distance with the vertices" This reverts commit753f1b7909. * Revert "Track the distances found in the douglas-peucker recursion" This reverts commite5361f8c22. * Revert "Fully deprecate -detect-shared-borders into an alias" This reverts commit0698aeb766. * Better tracking of whether we failed to make a full-detail tile * Put a bloom filter in front of the binary search for shared nodes * Forgot to take out this printf * Improve dispatch of tiling tasks * Still dispatch the biggest tasks first * Track zoom truncation in the strategies list in the tileset metadata * Prescan for small deltas before doing proper simplification * Revert "Prescan for small deltas before doing proper simplification" This reverts commitd1d8238b83. * Update version and changelog * Rename to --generate-variable-depth-tile-pyramid
