What do you mean by a proportional resize?

If you mean simply resizing the image and keeping it's aspect, you might want to
have a look at the way I did it.  I use Imlib to load and render the image. The
code can be found at:

I used a table and a drawing area to keep the image centered within the window.

However, if you mean keep the aspect of the image and resize the window to fit
around the image. You could catch the "size_allocate" signal from the image and
set the size of the window accordingly. The only problem here is the window will
behave 'weirdly' as it snaps to the aspect of the image when the window is
resized by the user.
