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)
    
3. changed envelope method to return vy value in datasource classes

4. features_at_point impl for shape and postgis plug-ins

a6994cfc45 Fixed up text placement. 
Removed the patch for better cornering from r365,

d7b94f5d8c Added avoid_edges property to shield and text symbolizers. 
If this is enabled, no shield/text symbolizers will be cut off
at the edges of the image.

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.

118e8f0d52 Added face_name parameter to text and shield symbolizers, 
which specifies the font face to be used for rendering.
New constructor is: text_symbolizer(name, face_name, size, ...)

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. 

Thanks to Robert Coup for the patch!

f76079f15b 1) Added line following labels. Use set_label_placement(POINT_PLACEMENT) or set_label_placement(LINE_PLACEMENT) on a text symbolizer. 
2) Added placement_finder class so labels try to avoid each other.
3) Added Shield Symbolizer which is essentially a combined image/text symbolizer.

bb235fa316 1.added projection transformation support based on proj4 (new dependency!!!) 
Map and Layer objects both have a new parameter 'srs', initialized to "+proj=latlong +datum=WGS84" by default. 
    
  Basic usage (Python):
    p = Projection("+proj=merc +datum=WGS84")
    point = p.forward(Coord(-2,51))
    ...        
2.reflected arithmetic operators for Envelope/Coord into Python
3.altered return policies for python objects
4.modified build system to require proj4 lib and headers
