[FEATURE] tile_post_process: add "merge" (drop) support for points
In the tile_post_process we can merge linestring or polygon. But there is nothing for points.
I see it like dropping points with same tags within a radius (rather than clustering.)
My current issue is with over numerous points generated from point_on_line geometry. I my use case I will even prefer point on merged line string, but looks very specific. (I build map with traffic sign/limitations for road sections.)
In the Java API there is a "setPointLabelGrid(size, limit)" utility that lets you cut tiles into a grid and limit the number of points that can appear in each cell in that grid. Would exposing that to the YAML layer work for your use-case?
It's a pretty coarse tool but has worked for most use-cases like this so far. I think a density-based post-processing approach would be good to but wondering if the existing capability would work in your use-case.
