8e071f84c7 1. Changed internal geometry representation (explicit support for multi geometries)
(FIXME : label_spacing is still, too slow!!) 
2. Re-use some agg objects.
3. placement_finder cleanups! 
4. Added support for 'building_symbolizer' - extruded polygons

8010d5433f 1. Removed srid from geometry class
2. Pass resolution to bbox query
3. Use variant<int,double,string> as parameter value e.g in Python:
	ds = Raster(file="/path/to/file",lox = 12312.4,.....)
   Added extractor facility to work with mapnik::parameter (C++):
	
	mapnik::parameters params;
	params["parameter0"] = 123.456;
	params["parameter1"] = "123.456"; // initialize with string extract double later
	
	boost::optional<double> val0 = params.get<double>("parameter0");
	if (val0) 
	{
	   std::cout << *val0;
        }
	
	
	// with default value. NOTE: there is no 'parameter2' in params
	boost::optional<double> val2 = params.get<double>("parameter2",654.321);
	std::cout << * val2;
        
	// 
4. Added Gdal factory method in __init__.py

        ds =  Gdal(file="/tmp/file.tiff")

bb235fa316 1.added projection transformation support based on proj4 (new dependency!!!)
Map and Layer objects both have a new parameter 'srs', initialized to "+proj=latlong +datum=WGS84" by default. 
    
  Basic usage (Python):
    p = Projection("+proj=merc +datum=WGS84")
    point = p.forward(Coord(-2,51))
    ...        
2.reflected arithmetic operators for Envelope/Coord into Python
3.altered return policies for python objects
4.modified build system to require proj4 lib and headers
