It does the same as repeating the size from the allocation event without
subtracting anything. It seems to make the panel grow by 2 pixels so I
get another allocation event 2 pixels bigger, and the panel grows and
grows. Basically, whatever I pass to gtk_widget_set_size_request, I get
another allocation 2 pixels bigger, so I have to test for that and
ignore it.

Yes, I suppose that could work in this case. I'll have to try it and see
if it then allows the panel to be reduced without that animation effect.
It wouldn't work for tgauge in its current form though, because that
wants to know how big a pixmap to put in the GtkPixmap, which in turn
presumably sets the size request.
