Again, my test case is pressing exit right after starting gcompris and 
observing events until the exit confirmation window is up.

I put some printouts to paint, and noticed the following: 
art_rect_list_from_uta() gives back three rectangles. Then 
gtk_widget_send_expose() is called for each of them. Number 0 is fast, number 
1 takes several seconds, and number 2 is again fast.

So, the time is spent in gtk_widget_send_expose(). What does it do? Does it 
call some callbacks in canvas where I could add more printouts?

Best regards,
Terje
