artemp 34d96f3ef2 shape.input - avoid expensive hit_test and instead use relatively cheap orientation test to distinguish
between inner and outter rings (Polygon/NultiPolygon) -- ref #2151  https://github.com/mapbox/unpacker/issues/324

```txt
A polygon consists of one or more rings. A ring is a connected sequence of four or more
points that form a closed, non-self-intersecting loop. A polygon may contain multiple
outer rings. The order of vertices or orientation for a ring indicates which side of the ring
is the interior of the polygon. The neighborhood to the right of an observer walking along
the ring in vertex order is the neighborhood inside the polygon. Vertices of rings defining
holes in polygons are in a counterclockwise direction. Vertices for a single, ringed
polygon are, therefore, always in clockwise order. The rings of a polygon are referred to
as its parts.

Build Status

Mapnik is an open source toolkit for developing mapping applications. At the core is a C++ shared library providing algorithms and patterns for spatial data access and visualization.

Mapnik is basically a collection of geographic objects like maps, layers, datasources, features, and geometries. The library doesn't rely on any OS specific "windowing systems" and it can be deployed to any server environment. It is intended to play fair in a multi-threaded environment and is aimed primarily, but not exclusively, at web-based development.

For further information see http://mapnik.org and also our wiki documentation.

Installation
