18209	Add GEOS functions supported by Shapely that GeoDjango lacks	Paul Winkler	nobody	"We don't have interpolate() or project() methods. Shapely does:  
http://toblerity.github.com/shapely/manual.html#linear-referencing-methods

  It can useful to specify position along linear features such as LineStrings and 
  MultiLineStrings with a 1-dimensional referencing system. Shapely supports linear referencing based on length or distance, 
  evaluating the distance along a geometric object to the projection of a given point, or the point 
  at a given distance along the object.

I don't know what else, if anything, Shapely has that we don't have, but I stumbled on not having interpolate today.
