[boost] Generic Image Library (GIL) accessing raw memory

Another question / observation on the GIL API.  When interfacing with
external code, particularly "C" libraries, it's often necessary to pass
a pointer to the memory managed by an image
(gdk_pixbuf_create_from_raw_data() in my case).  So far, I've been using

  &image[0]

to get a pointer to memory, but that's pretty ugly, and I'm thinking it
might not work for all cases.  Is there a better way to do it?  If not,
I'd suggest adding an "image::data()" method that would provide
canonical access to memory.  The choice of name is for consistency with
std::basic_string::data().

Cheers,
