def test_compare_rgba8():
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.
