I choose that name since I can imagine several types of image
iterators. Like a tile_read_iterator, multiple_scanline_read_iterator,
etc.

Reader class now has a typedef iterator_t. But still, what would I
call the scanline_read_iterator class?

Users are meant to include format specific header, like bmp_all.hpp,
or tiff_write.hpp, or png_read.hpp. So, I put all the other headers in
the detail folder even so some of them are not inside the detail
namespace.
