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
(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
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)
3. changed envelope method to return vy value in datasource classes
4. features_at_point impl for shape and postgis plug-ins
