00fd2a9f00 1. placement_finder.cpp
fixed 'for' loops to work correctly when geom->num_points() < 2
    always use prefix increment even for built-in types (good practice!)
    e.g ++i 

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')

   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.
