* 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 commitfec5e8354c. * 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 commitdb6bc27d9e. * Add --order-by and --order-descending options * Accept multiple --order-by and --order-descending-by sort keys
