Title: Geometry: add self-refining "ProgressiveLinestring"

This pull request would add a google-like self-refining polygon to OpenLayers. Especially very large linestrings take a lot of processing power if rendered as SVG. By adding some self-refining algorithm the amount of drawn vertices can be drastically reduced, resulting in a huge performance gain for OpenLayers.

The algorithm selecting the visible parts of the LineString is very basic and still has to be optimised.

I'd like some comments on this to continue working towards integation into OpenLayers.
