Comment (by Björn Harrtell):

 Putting 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.

 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?
