220bb3e99a Revert the patch to add a show_page flag to the cairo renderer and
replace it with support for rendering to a cairo context rather than
a cairo surface.

When rendering to a surface a show_page is done, when rendering to a
context it is not so that multiple renders can be done, possibly with
modified scaling and/or translation.

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!

Artem Pavlenko
2058f966b2 applied patch from Jochen :
1. The README talks about "scons.py", but it is just called "scons".

2. In demo/c++ there is a Makefile, but the readme.txt gives a command
   line to compile. Both don't work for me. One error can at least be
   fixed by adding -I../../agg/include to the command line.

3. When compiling Mapnik an error is thrown because of a redefined type.
   This was on an Intel 64Bit machine. Fixed by "typedef char byte" to
   "typedef uint8_t byte" in include/mapnik/global.hpp. I am not sure
   whether thats the right fix, though, I just guessed. :-)

4. include/mapnik/image_data.hpp needs
   #include <mapnik/octree.hpp>
   to compile

2. PostGIS plug-in - optional 'multiple_geometries' parameter to control how Multi* geometries built. 
3. MarkersSymbolizer (work in progress) to render vector shapes (markers) alonh a path with collision detection.

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

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

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")
