That was my first line of inquiry, except it doesn't seem to resize. I
can see this because if I leave a frame border on the parent
AspectFrame, it doesn't resize.

I tried putting the DrawingArea into a 1x1 Grid, in turn inside of an
AspectFrame, but it still doesn't resize.

Even if I remove the aspect frame and calculate the image dimensions
myself, there still seems to be no way I can find to reliably resize it
dynamically.

I can't believe resizing a widget in Gtk+ is this difficult. I think
I've tried everything by now. Viewports, AspectFrame, cairo, Gdk pixbuf,
subclassing and overrides. You'd think something like this would be
really straightforward. =(
