Hey Tom. Great idea. I definitely overlooked the small and obvious thing
this time. I totally forgot about the GtkAspectFrame. It makes a lot
more sense to use that in this case than going to all this trouble
subclassing GtkImage, overriding virtual methods, etc. So this is what I
came up with...

It works great, except for one thing. The GUI doesn't freeze thankfully,
but the image or aspect frame just keeps _growing_ and doesn't stop. I'm
guessing what's happening in the "draw" signal callback is I am resizing
the image widget, which in turn is resizing the AspectFrame widget,
which is in turn resizing the image widget, etc...
