d3ec70aff9 Return pre-r557 rendering of line aligned labels. (Not the code, the algorithm ideas) 
Spacing and no spacing line rendering are done by the same function.
Code is cleaner, performance should be equal or improved.
Text displacement is "Different", better in some cases and worse in others, I can revert it if wanted.
Old non spacing code is not yet removed as it is used by ShieldSymbolizer which I haven't investigated yet.
Individual character placement still has issues, that is my next task to fix!

37f49e29cc Applied patches from Martijn van Oosterhout: 
1. The first allows the user to add a <FileSource
name="foo">/home/bar/baz/</FileSource> to the beginning of the file
and then in any of the symbolisers you can say:

<FooSymboliser base="foo" name="bridge">
It it will refer to the file /home/bar/baz/bridge.

2. The second allows you to create Datasource templates at the top
level, which can be used later in the actual layers like so:
<Map>
  <Datasource name="db">
   <Paramaeter name="host">/tmp</Parameter>
  </Datasource>
  <Layer name="lay">
    <Datasource base="db">
      <Parameter name="table">points</Parameter>
    </Datasource>
  </Layer>
</Map>

And the host parameter will be used in the layer.

3. The third adds the "base" parameter to the raster and shape input
plugins. All it does is specify a path to prefix to the filename prior
to using it. Together with the above feature it allows things like:
<Map>
  <Datasource name="shapes">
   <Paramaeter name="base">/home/foo/shapes</Parameter>
  </Datasource>
  <Layer name="lay">
    <Datasource base="shapes">
      <Parameter name="file">places</Parameter>
    </Datasource>
  </Layer>
</Map>

And it will use the shapefile /home/foo/shapes/places

	>> save_to_file('test.png,'jpeg',im) # Explicitly save as JPEG

d38dedad68 + added GNU autotools build environment 
+ raster and gdal input isn't tested. Not working currently...
+ *-input.so plugins created. Change loader in source or link plugin to correct place
+ use pkg-config uninstalled feature
  -> define project root to PKG_CONFIG_PATH to use mapnik without installation
+ added various library checks
+ don't install fonts
+ don't use included AGG
  -> check for a installed libagg
+ Added Makefile for c++ demo
+ don't build any python wrapper stuff
  -> this follows if all other building works
+ added Anjuta file
  -> not needed to build anything, but helps much if you use Anjuta

	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;
        
	//

fixed 'for' loops to work correctly when geom->num_points() < 2
    always use prefix increment even for built-in types (good practice!)

2. agg_renderer.cpp 
    check for number points in geometries when 
    applying text/shield_symbolizer.

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')

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.

7cae55f73f * trim leading and trailing whitespace from all strings before 
rendering them as labels when using the text or shield symbolisers
  (blame my horrible datasets)
* correctly recognise the Postgis "text" data type (it was in
  postgisfs.cpp just not postgis.cpp) - my initial workaround to the
  above was "SELECT trim(from label) AS label ..." which failed
  miserably because it returned a text data type.
