    initial v1  
    11Putting some more thought into this I think I'm already doing quantization and it can cause problems in some cases as described at https://github.com/mapbox/vector-tile-spec/issues/58#issuecomment-173717621.

    3 I wonder if it's possible to quickly categorize input that can be problematic and what should be fine with simple quantization. If it's only about polygons with inner rings that are close to their exterior it should be detectable?

Polygons with inner rings that are close to their exterior it should be detectable. I think polygons small enough to risk revering winding order when rounding should degenerate to a point or line (already done with check_geometry_size but it's too naive).
