Hello,

I've been an Emacs user for a reasonable portion of my life and recently
decided I'd like to start contributing to GNU/Emacs development. With
the aim of starting off by scratching itches, I've thought before that
in image mode there should be a way of navigating around an image within
an *image-mode* buffer using the mouse. To this effect I've made the
following (albeit, trivial) patch that allows you to use the mouse-2
button to drag around an image that is larger than the window displaying
it.

I'm a relative newcomer to Lisp so you may judge my code to not be
worthwhile, however I'm always willing to receive constructive criticism
where it is due, and suggestions on how I can improve my coding style.

I read within etc/CONTRIBUTE that I needed to contact this list to
obtain forms so that the GNU/Emacs project may benefit by my
contributions, so to this effect I've been subscribed to the digest
version of the list for about a week. It's a bit scary for a newbie to
see all the arguments that go on around here.

Cheers,
Benjamin
