[OSM-dev] Overzoom - how to extract subtile from vector tile in mapnik

[Yuri Astrakhan]

Hi, I can't figure this out for some reason. Given a vector tile (PBF)
data, I need to extract a portion of that tile at a given x,y, with a given
width & height (or as a box). The extract will be treated as a full vector
tile of its own, and I might need to either extract it as PBF, or render as
an image.

Looking through the mapnik-vectortile
<http://mapnik.org/node-mapnik/documentation/#mapnik-vectortile> doc, I
don't see anything that would help me (image has a "view", but its not
available for vtile).

Thanks!
