* Add an option to generate label points in place of polygons
* Change all these places where I said "extent" but really meant "area"
* Revert "Change all these places where I said "extent" but really meant "area""
This reverts commit 403828d2f7.
* Add --order-smallest-first and --order-largest-first options
* Use Turf's center-of-mass algorithm for polygon label points
* If the label point isn't within the polygon, find one that is
* Don't choose a label point that is too close to a border
* Try a little harder to find an optimal label point
* Checkerboard which tiles labels are generated in, to reduce adjacency
* Use a label point for the general representative point for polygons
(Skipping the iteration to find one that is as far as possible from
the borders)
This makes the labels look better in many cases (like France at z1)
but unfortunately ripples into changing the sequence of polygons in
many tests, so the diff is big.
* Revert "Use a label point for the general representative point for polygons"
This reverts commit 2261adf05e.
* Checkpoint work on spiral labels
* Clip label spirals to the feature bounds
* Fix label test
* Be careful not to place spiral labels too close to borders either
* For spiral anchors, only check tile scale, not feature size
* Update test
* Only try to find a central label point for the largest ring
* In tiny polygon dust, keep the attributes of the largest feature
* Add an option to retain extra coordinate precision at maxzoom
* Make sure not to shift away the extra detail from coordinates
* Add an option to convert double-precision attributes to single
* Sort attribute values in tiles to make them compress a little better
* Slightly improve polygon simplification
By choosing a point that would be retained after simplification
to be the start/end point that always gets retained
* I regret making all of these tests involve polygons
* Add an option to specify the size of tiny polygons
* Fix accidental requiring of argument for --single-precision
* Guard against duplicate points when generating "sizes" for them
* Restore the intended behavior that tiny polygons don't get simplified
* Make the extra detail settable rather than always maximizing it
* Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)"
This reverts commit fec5e8354c.
* Add an option to prevent choosing a base zoom higher than the maxzoom
* Keep the drop rate high enough when the basezoom gets constrained
* Revert "Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)""
This reverts commit db6bc27d9e.
* Add --order-by and --order-descending options
* Accept multiple --order-by and --order-descending-by sort keys
