Support for Google Maps encoded geometries

When displaying polygons and polylines with GMaps, performance can be massively improved by using encoded geometries. It would be great for GeoDjango to support this:

  • a module to encode geometries and return a dictionary, so people can JSON-encode and send to the client, embed in templates, etc.
  • use encoded geometries in GoogleGeoAdmin

I've built a Python port of Mark McClure's Javascript encoder. There's also a matching C extension which has the same signature (think cStringIO vs StringIO). Other upsides: clean, pythonic, BSD licensed, unit tests. :)

Will be on Google Code somewhere in the next few days, or part of the gmaps-utility-library project.

This ticket has a large scope, the problems it describes are covered by an external library, and I don't see a good reason to merge it in Django.
