Ditch rint
...
Removes all usages of rint from the codebase, in favor of the standard
rounding and casting formula used throughout the codebase:
static_cast<int>(std::floor(<val> + .5))

A fix for two distinct issues associated with gdal featuresets, the first is overviews were not properly being utilized based on the resolution of the final image requested. The second is that allocation of far too much memory could be possible in GDAL to attempt to do resampling internally in mapnik. This now has a hard cap so that we allocate less memory in these situations but are still able to resample internally in mapnik.

[GDAL plugin] Add support for non-alpha mask band
...
GDAL can support non-alpha mask band, such as a TIFF IFD with
Subfile type=transparency mask. This can be typically used to
create a GeoTIFF with YCbCr JPEG compression for RGB bands and
DEFLATE compression for the mask band.

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.

Move image_data.hpp to image.hpp and renamed most everything from image_data to image alone. This might lead to the need to clean up some variables that are currently named image through out the code at some time, but I think in the long term is much better as image is a better name for the base class.
