438bfad732 + factory : variadic templates based implementation ( requires c++11)
+ image_reader : stream based reading interface (boost::iostreams)
+ register additional png and jpeg readers with following sigs :

  ```
  std::auto_ptr<mapnik::image_reader> reader(mapnik::get_image_reader(buffer,size));
  // buffer - char const*
  // size - size_t
  ```
+ initial type_from_bytes implementation (TODO: add more types)
+ python : mapnik.Image.fromstring(str) mapnik.Image.frombuffer(buf)

77e585895f + add premultiplied_alpha method to image_reader
* tiff - TIFFTAG_EXTRASAMPLES
  * png  - non-premultiplied alpha (http://www.libpng.org/pub/png/spec/1.1/PNG-Rationale.html)
  * jpeg - no-alpha channel, ensure pre-multiplied model
