Herm... what you want is to pack your image into a Gtk::ScrolledWindow
and set the policy to ('automatic','automatic')

Then pack the ScrolledWindow into your main window.

Use a function to calculate the size of your image... set the usize on
the main window to be that size, and you should have no scrollbars... but
if the user resizes, the scrollbars will appear.  You MAY need to set the
window size slightly (1 or 2 pixels) larger than the image size to
compensate for the window borders, I am not certain, but this is a fairly
simple thing to play with and figure out.
