I see, the widget's handler runs first.

Anyway, by current one I meant more something like the
last one used.  If the widget already has stored the new
allocation, you can always keep your own copy of the
GtkAllocation elsewhere for comparison.

Or just subclass GtkWidget and get your own size-allocate,
the widget implementation seems to be trivial here
(boilerplate code plus one gdk_draw_pixbuf() in
"expose-event").
