I dont mean the first "configure_event" (coming after drawing area get 
realized).

I just noted that when your drawing area is packed into GtkAlignment with
xscale=yscale=0 its size *will remain unchanged* when you are trying to 
resize
container. But you *will receive "configure_event" signal* every time the
GtkAlignment *will try to resize his child. I had some troubles with 
this in the
past when I used GtkAlignment with zero scales and had expected that 
configure
will not be emitted when resizing such container.
