… way that saving images is processed in image_util.hpp and image_util.cpp. * Changed the passing of rgba_palette to a shared_ptr in order to better facilitate the use of a visitor pattern. * Moved PNG util processing into its own set of files so that image_util_impl.hpp would not have to depend on HAVE_PNG.

…lders. Added the intial concepts for an image_view_any variant.
…d. Mostly modifications to the image_util_* files. Different processing based on the image type is now possible, and save_to_stream now could possibly accept grayscale with out breaking existing code.

…ventual use of image_view_any and image_data_any, but for a limited time supports the passing of image_view_rgba8 and image_data_rgba8. Ref #2633
…he 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. Ref #2633

* 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. Ref #2681
…. Added several new SSE methods for unsigned integers.

…t types, added tests for all the new data formats with get and set in python.

This update is in Ref #2649. It provides an update to markers and their processing such that: * All shared_ptrs are no longer required around markers * Markers are now const
