[gdal-dev] Polygon operations

[Metabase Account]

I might be thinking of this incorrectly, but if they're done in 2D without
any spatial consideration, inserting additional vertices in between
shouldn't have an effect on behavior right? However it does seem to have an
effect when using operations such as warp with the polygon as the cutline.
