9fe4a94c98 Added minimum_distance property to text symbolizers. This prevents the same label from appearing within N pixels (across features).
Shield symbolizer is now a subclass of text symbolizer.
Some small improvements to text rendering.
Fixed up placement finder for horizontal placement.
Cleaned up placement finder.

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")

e016bd61f8 Added transcoder based on iconv. Internally we use UCS-2 at the moment.
* Postgis plug-in determines encoding by querying 'client_encoding' parameter (libpq). 
 * Shapfiles (dbf!) don't store character encoding information. Users can apply 'encoding' parameter at datasource creation stage (defaults to Latin1 (ISO-8859-1))
 * Raster plug-in utf-8

4d4e9f5d91 Tiling patch from Toby allows for a selected pixel region within an extent
to be rendered. This allows for a large extent (larger than can be
rendered into a single image in memory) to be rendered out as tiles.
Since the full extent is used for the placement calculations text
crossing tile boundaries will be consistent.

This method is a little inefficient when a large number of labels need
placed, an improved method would be to cache these placements between
tiles, but the attached is a start.

c++ users should simple call the render method with a start X and Y
coordinate specified, 

for (int TileX = 0;TileX < 5;++TileX)
{
	for(int TileY = 0;TileY < 5; ++TileY)
	{
		int TileSize=250;
		int StartX = TileX*TileSize;
		int StartY = TileY*TileSize;
		
		Image32 buf(TileSize,TileSize);
		agg_renderer<Image32> ren(m,buf,StartX,StartY);
		
		ren.apply();
		char name[324];
		sprintf(name,"tile_%d_%d.png",TileX,TileY);
		ImageUtils::save_to_file(name,"png",buf);
	}
}

python users should call render_tile_to_file

for y in range(tile_count_y):
	for x in range(tile_count_x):
		if not os.path.exists("tiles/%d/%d/" % (map_scale, y)):
			os.makedirs("tiles/%d/%d/" % (map_scale, y))
		render_tile_to_file(m, x*tile_size, y*tile_size, tile_size, tile_size,
'tiles/%d/%d/%d.png' % (map_scale,y,x), 'png')

f1393cc019 1. hit_test implementation for geometry objects:
bool hit_test(double x, double y, double tol);
       
2. added image_view(unsigned x, unsigned y, unsigned width, unsigned height)
   allowing to select region from image data e.g (in Python):

    im = Image(2048,2048)
    view = im.view(0,0,256,256)
    save_to_file(filename,type, view)

889ac41694 Patch from Toby: adds a maximum angle delta for text placement (if the
angle changes too much between characters it finds an alternate
placement), this is specified in the max_char_angle_delta property in
radians (feel free to change it to degrees).

It also improves the text placement around corners trying to minimise
the distance between the center of the character and the line on each
side. This is the major portion of the patch.
