I'll discuss it with Lubomir. I rather believe that we should divide
gil into seperate modules. One for the core part, meaning the
infrastructure code without specific code for color spaces, etc. And
then, there should be extensions for all the color spaces, io, image
variants, algorithms, etc. Also, gil might consider having it's own
review procedure. This might fasten up inclusion of new extensions and
also takes burden away from boost. After all the extensions are
gil-specific and don't impact boost very much. What do you think?

I'll change the code, asap.

read_and _no_convert is defined in conversion_policies.hpp.

I was thinking of adding that, as well. But it would introduce the
dependency to boost::filesystem. Not sure if that's advisable since
the io lib wouldn't be header only anymore.

Thanks for your effort,
