124362d2d4 stop correcting geometries at decode time 
- the original motivation for this was to avoid needing to
   mutate a copy later on (for operations needing correct winding order)
 - but mutating a copy is looking feasible, so removing this now.

2b8bd59d82 A large set of updates: 
* Added new gray data types adding those to the variants and updating all the code necessary for them
* Added basic SSE to the image compare method, (only for RGBA) must be enabled with the -DSSE_MATH flag this is not yet put into the build process in any location.
* Fixed the resulting image for some TIFF visual tests, most likely they were incorrect due to fixes in TIFF reader
* Added some MAPNIK_DECL where necessary to grid rendering.
* Added support for more data types in GDAL plugin with grayscale images.
* Added views for all the new gray data types
* Updated python bindings for new gray data types.

4184f75011 Moved premultiply and demultiply out of image_32 and other parts of the code. The image_data object is now responsible for keeping track of its own premultiplied_alpha status. Created a new utility method in image_util to preform premultiplication. 
Added visitor pattern to several different methods as well to prepare for image_data_any including compositing.

4f93b7c879 shape.input - avoid expensive hit_test and instead use relatively cheap orientation test to distinguish 
between inner and outter rings (Polygon/NultiPolygon) -- ref #2151  https://github.com/mapbox/unpacker/issues/324

```txt
A polygon consists of one or more rings. A ring is a connected sequence of four or more
points that form a closed, non-self-intersecting loop. A polygon may contain multiple
outer rings. The order of vertices or orientation for a ring indicates which side of the ring
is the interior of the polygon. The neighborhood to the right of an observer walking along
the ring in vertex order is the neighborhood inside the polygon. Vertices of rings defining
holes in polygons are in a counterclockwise direction. Vertices for a single, ringed
polygon are, therefore, always in clockwise order. The rings of a polygon are referred to
as its parts.

af4c2620aa Ignore overviews with 0 scale in pgraster 
refs #2551

Postgis raster_columns view is returning NULL values for raster
overviews with large scale factors. That issue in postgis is described
in http://trac.osgeo.org/postgis/ticket/3006

This causes two main problems:

  - The first overview with scale = NULL is wrongly chosen for rendering
    always

  - The messed up scaling factor causes the render symbolizer to spent
    an insane amount of CPU and memory to render a messed up tiles.

The patch in postgis is expected to be released with the new version, a
few months from now.
