 a) This is a question about _how_ to program with GTK+, not 
    discussion of improving GTK+, so the question should 
    be on gtk-list or gtk-app-devel-list.

 b) Look at the section about drawing in the tutorial (the scribble
    section). It will explain that you basically always should be
    doing all your drawing in an expose handler.
