rebuild cairo block static libs i386 and x86_64 fat for os x

The previous archives seem to indicate the versions of the libraries being used are now very well aged and would be: libpng-1.4.3, pixman-0.19.2 and cairo-1.10.0. I can't speak to the versions and needs, so rather than potentially introducing an issue by updating them, I just rebuilt the aged versions with both i386 and x86_64 slices and 10.7 as the deployment target.
jam support for 3D textures into existing 2D path

This is not likely the right spot for 3D texture support, but a whole new class for 3D textures seems like overkill when this works for my needs. Hopefully someone can better generalize and realize GL_TEXTURE_3D support.
